Just curious, what are your motives for the MS? Are you planning on working in public accounting after graduation? If that is the case, then I would say that you should just check to see at which schools accounting firms recruit (i.e. if you want big 4, then look to see which schools the big 4 visit). Its not as "competitive" as you would think. In my mind, if I was in your situation, I would try and see what gives me the biggest bang for my buck as far as schools and exposure to accounting firms go.
BTW, your GMAT score would be pretty good for most programs I would think.
