Salt-Stack mysql_grants.present Underscore Wildcard - mysql

Question

I'm using Salt to provision cloud servers but I'm having problems with MySQLdb producing the correct permissions for MySQL. If I was executing the SQL directly it would be:
GRANT ALL ON `install\_%`.* TO 'installer'#'localhost';
The sls file contains:
installer_local_install_grants:
mysql_grants.present:
- grant: all privileges
- database: install\_%.*
- user: installer
- host: localhost
- escape: False
Which produces this error:
Function: mysql_grants.present
Result: False
Comment: An exception occurred in this state: Traceback (most recent call last):

query = query % db.literal(args)
TypeError: * wants int
With debug in salt turned on the relevant line prior to submitting to MySQLdb is:
Doing query: GRANT ALL PRIVILEGES ON install\_%.* TO %(user)s#%(host)s args: {'host': 'localhost', 'user': 'installer'}
So it seems Salt is outputting the correct code but MySQLdb is not handling some part of the query correctly. The query is missing the back ticks but I'm really not sure how to get those in.
With the escape removed or set to True the grants look like:
+-----------+-----------------+------------------+
| Host | Db | User |
+-----------+-----------------+------------------+
| localhost | install\\_\% | installer |
+-----------+-----------------+------------------+
When it should look like:
+-----------+-----------------+------------------+
| Host | Db | User |
+-----------+-----------------+------------------+
| localhost | install\_% | installer |
+-----------+-----------------+------------------+
