I’m not sure how much more useful that is than just using HN’s automatic ranking for comments, at least outside of parent comments on posts; As far as I can tell, child comments are always ORDER BY score DESC.
Even for top level comments, HN’s algorithm for ranking is pretty useful for assigning “worth”
On posts there's an attempt to suface later comments (with fewer points) so the comment section isn't dominated by earlier posts.
Ordering by score DESC only gives you relative point information, not absolute. Theres additional signal if the top comment has 100 points vs only having 3 (and the bottom post also having 100 vs 1).
