I imagine that it comes down to demonstrated (or expressed) ability, acumen, motivation, and interest. But it depends on how heavily they lean on their heuristics. If you're interested I wouldn't let your fear that they won't accept BA's stop you from applying. I have a BS in Economics and am currently enrolled in a Master's in Computer Science. I mention that because I know there are plenty of BA in Economics programs around...and I can't imagine they differ that much from the program I graduated in.
