How does Stanza sort in Collections?

[mkelley]

Now that I have Stanza installed and working great on my iPad (IOS5 after all) I really like it. No eReader I've found offers the kind of formatting possibilities it does (love the line and paragraph spacing and, something I can't find anywhere else, the paragraph indent).

I also love the collections but I can't quite figure out how the books are sorted within collections. I thought it was by title, but is it the filename, the Title metatag, the sorted title metatag, or something else I'm missing?

Anyone here know? I can do some experimentation, but I was hoping someone could save me the trouble.
