Help me figure something out.

How tall are you? Cyclocross bikes in general tend to run big (bottom bracket is up higher), so while it's probably the equivalent of a 46cm bike, it's got the measurements of a 48 or 49 cm frame otherwise. I'm also short-torsoed.
Let's just say I can get my hands easily on an extra-small (coworker has one), but a small is harder to come by. I have tried their road bike in a size small (same TT and seat tube angle measurements, IIRC) and it could work with a shorter stem, but I'd be more comfortable on their XS, probably.

I'm anywhere from 5'2 to 5'4 depending on the day and the doctor. Gosh, this buying a bike thing just gets more and more complicated, though. How disheartening. Do you know the standover height for the CFA?

edit: This blog recs the Cross Check for people under 5', and this site and this thread also list possible CX bikes for shorties.
