I don't actually recall anyone from Google saying authorship would help you rank, just that it does have a tendency to increase CTR of pages that already rank.
and "authority signature value" for authors
DS: That’s why you don’t use Google +1s.
MC: Yes, for the same reasons. It can be sparse. It can be unreliable. That’s why I push back when you ask me about this.
However, I could see Google bumping you up a spot or two if it's already associated your name (as verified with a Google+ account, of course) as authority on a certain topic.
