The way this is done was changed recently (like say on Wednesday).
What happens now is that the comment is logged with a value of "yes" for karma_bonus. A user can adjust the value for what this bonus means (by default it is +1). When you look on you own page you see the raw score, which is 1.
We have been getting rid of the +1/-1 and such type bonuses and going to a system where the user can decide what they want to apply for a bonus.
