My OAR was a 49 (I don't know what all the #'s were...). I can tell you that it was a fluke that I even qualified for NFO. My recruiter offered it to me when he called me to tell me I was not selected for Supply (reason given was too many violations on my record...TRAFFIC VIOLATIONS if you can imagine!!!!). The Navy was waiving requirement for minimum score on the biographical profile portion that I originally did not score high on.
My GPA was about a 3.2 (I think....its been so long since I put my package together!!!). My major was Spanish, but I also have an MBA, which I am sure helped.
As far as my PRT scores, I didn't do great. Better than passing, but I think I scored in the Good Low/Satisfactory High across the board.
In any case, its all about timing. Seem to be some people on this site who did better than me across the board, yet did not get accepted.
I have a friend from high school who is now an accessions officer. I saw her a month or two ago and she told me that it is more competitive now than ever. She also mentioned (can't say she is not brutally honest) that had I turned in my application any later than I did (Mar 02), that I probably wouldn't have even gotten my slot.
Good luck!!!
