I think that if we could coordinate perfectly what we mean by good comments, and each comment has a score between 0 and 1, then we should all upvote a comment with a positive score with a probability equal to its score, and downvote a comment with negative score with probability equal to its negative score.
This would cause the karma assigned to a post to drift over time unboundedly with expectation of: (the traffic that it recieves)*(the average score of voters), which seems problematic to me.
Nitpick: maybe you want the score to run between −1 and 1 and voting probability to be according to the absolute score? I’m confused by your phrase “comment with negative score”.

“negative score” means the negative of the score you give. If you give −1/2, you downvote with probability 1⁄2.
If we could coordinate perfectly, we’d delegate all the voting to one person. Can you try solving the problem with weaker assumptions?
