As I'm sure you know, there are numerous other things besides scores that admissions committees look at in terms of offering you a place. For example, how your interests match up with the professors in the department.
I believe I was in a situation not unlike yours, in that I went to a small liberal arts school in the mid-west for my BA and am now getting a Ph.D. studying the modern Middle East at an Ivy league school. Scores aren't as important as you think - although you should be aware that if you are applying to a history department instead of a Middle Eastern Studies or Near Eastern Studies department your chances will be much reduced. Some schools - NYU and Harvard - have joint programs for History and Middle Eastern Studies, with students getting spots in both departments, while funding comes from one. This is nice, but can be competitive. I've heard through the grapevine that NYU had 150 + applicants for 5 spots. Other schools like Princeton, Arizona, or Michigan have Near Eastern studies departments.
In the end, getting into schools is a fairly opaque process, but I can say that scores at this level matter less than one might think, or at least that is my impression. How your research interests match with those of a professor, work you have produced so far, languages you know, research time, fellowships received and a host of other things are just if not more important. But, in my opinion, the most important thing is to have a professor that is willing to go to bat for you on the admissions committee.
