I had a positive vote in the c# tag badge category which raised my category up vote count. The up vote was undone but I still had it in my up vote count in the tag.

Tag score statistics are cached daily (http://meta.stackoverflow.com/tags/bug/topusers) see bottom of the page.

It is too expensive to calculate these puppies on the fly (same cache is used in the tag wiki page - and hopefully in the user page some day)

There's another issue going on though, the question/answer votes themselves (the denormalized versions) aren't being updated correctly in all cases, a vote later usually fixes it which makes me think deadlock/rollback issue still...are you guys aware of that lingering issue? –  Nick Craver Oct 17 '10 at 11:53

The data is cached to avoid the expensive of hitting the dbase frequently. It will take some time for the cache to refresh.

There's something wacky going on with vote denormalization, this is definitely a bug at the moment. I assume it's still a remnant deadlock issue where the normalized vote total update gets rolled back...but whatever the cause I'm seeing it a dozen time a day as well.
