Possibly still due to the time decay function. I don't know exactly when each comment was created, but pg's comment may have been more recent (within 24 hours). I haven't looked at the inner workings, but I imagine that upvotes might also be weighted more for how recent they are. Example: pg's comment may have received 17 upvotes within a minute of posting, and his post was 4 hours after brh's, and brh's upvotes happened slower, or before pg's comment.

This is all speculation. Maybe someone who has looked at the code could confirm or debunk this.

I not certain, I am under the belief that the function that is applied to the comments pages is very closely related to the function that is applied to the main page.

I.e. a bit of time decay, overall karma activity (Karma score + comment karma score), number of sub threads, etc.
