When I applied, I was in a similar situation to you - GPA was not perfect due to some high-level math (physics/math minor, yay for quant backgrounds). I had the exact same quant score you did. It ended up being fine in my case as I'm in a top program in my field, but as always, ymmv.
Obviously we're in slightly different subareas, and social is really competitive (hell, what isn't these days). In the end, it's up to you if you want to retake. If you have the spare cash to retake it, I don't think it would hurt. Worst case, you do worse and just don't send out those scores. But on the other hand, if your score is already on-par/above averages for admitted students, you may be fine as you are.
