Swip, yes that will put them in alphabetical order. The DSTT puts them in order placed on the card sort of. To be more accurate, it displays them in the order they appear in the filename table, which isn't always the order placed on the card (but usually is). Sometimes if you replace a file with another file it puts the new file in the same place as the previous file, particularly if they have the same filename.
@Jax: Some people swear by Fatsort but I haven't had much luck with it. It's corrupted my microSD and I've had to reformat. This method is probably just as fast and I've never had problems with it, plus you don't have to use any other software for it to work.
