I don't know if they have a name, but the "points" which show up next to tag on your stats page (and on the leaderboard in the tag stats page) don't seem to be affected by accepted answers.
For example, if I provide an answer, and receive no upvotes for it, but it is accepted as the answer, don't you think it should add a point to your tag stat?
An example: if you look at the tag stats page for XNA (http://stackoverflow.com/questions/tagged?tagnames=xna&sort=stats&pagesize=50), there are two columns. One is the total number of answers provided. The other is "total score", which is the total number of upvotes which you have received (http://stackoverflow.com/search?q=user%3a5416%20[xna]&page=1&tab=relevance). My score would be higher (even if slightly so) if accepted answers were used in that "total score" because there have been a few cases where my answer is accepted, but no upvotes were received :-)
