I haven't looked at the source for this website, but I would assume that one of the factors that gets used in display ordering is user average karma. A user with higher average karma is, by some mathematical analyses, more likely to produce an interesting post than one with lower. You guys have nearly identical total karma, but the top user has an average post score of 6.48 - yours is only 2.53. That's my guess, but like I said, I haven't checked out the source.
