Buddypress Member sorting

For my company’s buddypress plugin, we have the Achievements plugin as well. The only issue is that in the members section (http://community.copypress.com/members/) it sorts by the most recent member. Instead, we’d like to sort by the members with the most badges and certifications. I’m not sure how to do that. I have a sneaking suspicion that it is in the members-loop.php file or the achievements.php file but I’m not sure as to how to do so. Any help in this regard would be much appreciated.

Thank you.
