Thanks for the heads up; I will see what I can do. :)

I am indeed using the Chrome extension, but it only updates comment scores every 10 minutes while on HN as not to slow down the HN reading experience. :)
I don't have 1.5 to test on, but the Greasemonkey script should work, or you can email me at hnpoints at gmail and I'll try to help you get it working.
As an early adopter, it's quite likely that you'll see comments that are missing scores. This occurs when there is insufficient data to even make an approximation for a comment.
I can see the points on your reply, and the number of points on this comment should show up for you. As more users start using HNPoints, more comments should show scores.
