We had this discussion back when the points were being hidden, and I went through a few posts with many comments to see whether it would be possible to find the good comments based on where they were in the thread.
It turned out that because of the threaded comment system you get very little information about which comments have many votes and which don't. In the sample I checked it was impossible to get any idea of how popular a comment was around 50% of the time (this comment for instance, which is currently the only child to your comment could hav 0 upvotes or it could have 100. There's no way to know)
The solution, I think, is some sort of "unthreaded" view (with link to the contextual "threaded" view). Because, even if you do see the score, it is unlikely anyone will notice a +1000 answer to a -2 top level post when there are 20 of the latter.
The numbers themselves don't (and shouldn't) matter - only the rank.
