I think you should retake the GMAT and use all 5 options provided to submit your score. Your GPA is good, so if you keep the current GMAT result, it'll be quite regretful.
P/S: I'm not a consultant and don't have experience either. I am also applying for an MSF program this year.
Thank you for your comment. That means I will have to take the fourth exam, the process wasn't going easy for me. I don't mind taking more exam but I'm not sure if I can get, let's say, about 130 more scores in about 1 month, and my chance to get admission this year could be reduced if I miss two application rounds.
Anw thank you and wish you luck with your application to MSF program!
