Try setting up your folder/files like this:

Battlestar Galactica (2003) - S01E01 - 33

Battlestar Galactica (2003) - S02E02 - Scattered
And so on. You’ll probably need to do the Plex dance to clear up the database. Once everything is set up, click on Battlestar Galactica and then click on Edit→Advanced and under Episode Ordering, select TVDB(aired)
For some odd reason, if I don’t add the tvdb id, I can only select TMDB episode ordering.
