Hi rshih,
Thanks for writing in. Given your work experience in Accounting and hedge funds, it's likely that you can point to areas where you use Quant skills in your everyday job. Plus you can ask your recommenders to mention your quant skills in their letters. The schools you are looking at are quite competitive and will likely notice your Quant score, but your overall score is in good enough shape that you can likely balance it out with other strengths.
Given the number of schools you are focusing on and your desire to submit in R1, I suggest you shift your focus to essays, rather than reinvesting dozens of hours into the GMAT again.
Good luck!
Daniel Richards
