I don't really think anyone's going to be able to give a definitive answer to your question; the thing is, it will depend on how active you are. I'm short like you (5' on the nose!) and I find that I can eat up to 1500-1600 calories a day and still lose (of course, that depends on my activity level for that particular day.) I power walk 90 minutes a day, five or six days a week, plus I work out at the gym for 90 minutes two or three days a week.
Like someone else said: What keeps you in the 110-120 lb range will be specific to you and your activity level, and you're really going to have to experiment with it once you get there to see what works for you. I haven't reached maintenance yet, but I know from weeks where my weight has stayed the same that I can eat quite a bit more than the 1200-1300 calorie range that I keep seeing everywhere and still maintain my weight. And who knows -- that might change totally once I get to maintenance! It's a trial and error thing, I think.
