I can speak for my experience as an international applicant, hope it helps.
I had a low Verbal (530) and 800Q, but that did not stop me from being accepted in a top-5. However, I had a strong writing sample (according to one member of the adcom) and a good TOEFL (109). Not to mention the LORs, that I am sure helped. Perhaps, most importantly, my SOP describes someone very involved with quantitative methods.
In retrospect, I should have put more effort to achieve a 650+ score on Verbal. Things would have gone much more smoothly and now I would have a better rate of acceptance (30% so far).
