I'm trying to set up the player list so that it's organized based on ranking ladder (so Owner is at the top, then Admin, etc.), however, it seems no matter what I do I can't alter the order that TAB is organized. I've set the rank tag, so the ladder works correctly (I can use /demote and /promote effectively), so I don't think that's the issue. How can I do this successfully?

EDIT: I've also tried a variety of different alphabetical changes to see if that's what is changing it. Like changing the name of the rank to aOwner, bAdmin, or changing the prefixes from Owner to AAOwner, both which don't work.

PEX doesn't do this.

Could this be tagged as a feature request, then?

@zml2008 will make the final decision on that, but I've labeled it for ya. ;)

He may remove the labels and/or close it after he sees it.

This is not in the scope of PEX. PEX provides permissions and option storage to other plugins, and does not affect game behaviour itself. Sorting playerlist by rank is not impossible to do, but would be the job of another plugin that would get information from PEX/Vault
