When I enter to Community/Tournaments/Players, I see a few statistics about players. I would introduce six arrows near Wins, Losses, In-progress etc. to allow sort players by every data incremental or decremental. By default I would sort by current rank, what means for me:
Losses(dec) => Wins(inc) => extra stats => Team(inc) => Player's name(inc).

In extra stats I would make new scoring system based on:
all Wins => head-to-head results (in groups of more than two players sum of wins in this group, if partially fixed then divide into new groups etc. until can be resolved) => Sonneborn-Berger score => progression => (maybe also Culmulative score)

I recommend this sequence, but we can discuss about it.
Next thing is whether to add new columns and let players see extra statistics or hide them.

I am sure that it would be great ease and relief for players who alalyze score in every events like P/R Leagues.
