Sort order on TV Show episodes

Help!

I am trying to figure out how to make iPad sort episodes by episode number rather than strictly by alphabetical order.

I bought the original Wifi Ipad on Apr 3. Transferred all my episodes (which are all coded correctly with Season and Ep #) and when I would select "24", they would all list out by episode # rather than sorted by title. Same with 5 other TV series.

I returned my Wifi and now own a iPad 3G and put everything back on it, but no matter what I try, everything is sorted by title, which makes watching TV shows in order completely useless.

I know some will say "just add a 1- in front of the title." You shouldn't have to do that.

Anyone know the trick to get iPad to sort by Ep#?

thanks!
