Sorting by Release Type tag

I have no idea why I'm having so much of an issue with this. I've got a Release Type tag setup in Mp3tag with the variables

Album
Album;Live
Album;Compilation
EP
Single

Etc, but for the life of me, no matter how many posts I read, I can't seem to figure out how to sort via those tags in Musicbee. Can anybody break it down step by step when they have time?
