Answer 1

I believe you are trying to use oauth1 when oauth2 is required.
there already is a unanswered request about that here.
Implementing oauth 2 with Google app script is really a pain, so I made an attempt to build a library that could answer the need (dioxygen library) - it work a little bit like the oauth2 playground but it's less pretty.
With a little work you should be able to adapt it to your need with blogger.

Answer 2

I tried Harold's library, but after successfully retrieving OAuth token, I ended up with the same error.
But, when I issued the same JSON request as in my script through the API Explorer, it was processed:

[UPDATE]
I am taking it back. This code works. I just replaced the payload variable and put the JSON request straight into URL fetch options. So there was some problem with passing that payload variable into options variable.
function testBlogger() {
var payload =
{
"kind": "blogger#post",
"blog": {
"id": "YOUR_BLOG_ID"
},
"title": "New post",
"content": "With content..."
};
var options =
{
"method" : "post",
"headers" : { "Authorization" : "Bearer YOUR_ACTIVE_TOKEN"},
"contentType" : "application/json",
"payload" : '{ "kind": "blogger#post", "blog": { "id": "YOUR_BLOG_ID" }, "title": "New post", "content": "With content..." }'
};
try {
var result = UrlFetchApp.fetch(
"https://www.googleapis.com/blogger/v3/blogs/YOUR_BLOG_ID/posts",
options);
Logger.log(result);
} catch (e) {
Logger.log(e);
}
}
