Re: Sorting fields with letters?
Tried using the ord() function, but it was the same as the standard sort. Do I just need to bite the bullet and reindex everything? Thanks!

Well, yes. You probably have a string field for that content, right? so the content is being compared as strings, not as numbers, that why something like 1000 is lower than 2.
