SQL Server order desc and also show 6/6 - sql-server-2008

Question

I have a 3 columns in a table named col1, col2, col3 containing integer values. there are 4000 + rows. there is three parameter #first, #second , #third. I want to get rows who has match according to this parameter. The query is giving results but it is not giving me 3/3 or if there is no match it is not showing and also I want to make it descending order.
My output should be like this
table :
col1 col2 col3
3 4 5
1 2 2
7 7 9
3 2 3
1 8 9
1 2 3
first = 1 second = 2 and third = 3
3 / 3 1 ( as sixth row contains 1, 2, 3)
2 / 3 2 ( as second row and fourth row )
1 / 3 1 (fifth row)
0 / 3 2 (ist , third )
(
SELECT count (CASE WHEN col1 = #First THEN 1 ELSE 0 END +
CASE WHEN col2= #second THEN 1 ELSE 0 END +
CASE WHEN col3 = #third THEN 1 ELSE 0 END
)AS "NUM_OF_MATCHES" ,
CAST( CASE WHEN col1 = #First THEN 1 ELSE 0 END +
CASE WHEN col2= #sec/ond THEN 1 ELSE 0 END +
CASE WHEN col3 = #third THEN 1 ELSE 0 END
AS VARCHAR(10)) + '/ 3'
AS "match"
FrOM dbo.FormsDataRowFormat a
where ( SELECT CASE WHEN col1 = #First THEN 1 ELSE 0 END +
CASE WHEN col2= #second THEN 1 ELSE 0 END +
CASE WHEN col3 = #third THEN 1 ELSE 0 END AS "NUM_OF_MATCHES" ) >= 1
group by ( CASE WHEN col1 = #First THEN 1 ELSE 0 END +
CASE WHEN col2 = #second THEN 1 ELSE 0 END+
CASE WHEN col3 = #third THEN 1 ELSE 0 END )
)

SELECT
'0/3' AS Matches,
SUM(CASE WHEN (CASE WHEN col1 = #first THEN 1 ELSE 0 END +
CASE WHEN col2 = #second THEN 1 ELSE 0 END +
CASE WHEN col3 = #third THEN 1 ELSE 0 END) = 0 THEN 1 ELSE 0 END) AS NumMatches
FROM FormsDataRowFormat
UNION
SELECT '1/3' AS Matches,
SUM(CASE WHEN (CASE WHEN col1 = #first THEN 1 ELSE 0 END +
CASE WHEN col2 = #second THEN 1 ELSE 0 END +
CASE WHEN col3 = #third THEN 1 ELSE 0 END) = 1 THEN 1 ELSE 0 END) AS NumMatches
FROM FormsDataRowFormat
UNION
SELECT '2/3' AS Matches,
SUM(CASE WHEN (CASE WHEN col1 = #first THEN 1 ELSE 0 END +
CASE WHEN col2 = #second THEN 1 ELSE 0 END +
CASE WHEN col3 = #third THEN 1 ELSE 0 END) = 2 THEN 1 ELSE 0 END) AS NumMatches
FROM FormsDataRowFormat
UNION
SELECT '3/3' AS Matches,
SUM(CASE WHEN (CASE WHEN col1 = #first THEN 1 ELSE 0 END +
CASE WHEN col2 = #second THEN 1 ELSE 0 END +
CASE WHEN col3 = #third THEN 1 ELSE 0 END) = 3 THEN 1 ELSE 0 END) AS NumMatches
FROM FormsDataRowFormat
For input data:
/--------------------\
| col1 | col2 | col3 |
|------+------+------|
| 8 | 7 | 1 |
| 5 | 7 | 1 |
| 4 | 4 | 4 |
| 4 | 5 | 2 |
| 4 | 6 | 2 |
| 2 | 2 | 3 |
| 5 | 2 | 1 |
| 2 | 7 | 7 |
| 2 | 1 | 3 |
| 1 | 2 | 3 |
\--------------------/
with:
#first = 1
#second = 2
#third = 3
gives output:
/----------------------\
| Matches | NumMatches |
|---------+------------|
| 0/3 | 6 |
| 1/3 | 2 |
| 2/3 | 1 |
| 3/3 | 1 |
\----------------------/
Edit - Dynamic SQL solution:
Following your comment clarifying that the number of columns is dynamic (between 3 and 6 inclusive), below is a dynamic SQL solution which will handle any such number of columns.
Note however that dynamic SQL is probably not the best solution to this problem, especially if it's something which will be repeated many times and/or runs on very large datasets. However, it's the only way I know to achieve this, so I wanted to include it (and would be very happy to see better solutions from other users!).
