This is so infuriatingly unfair. I think that you should ask the College Board to delete the score that was taken without accommodations, so that it won’t appear if she decides to send her SAT scores. They should also refund your fee, and get her a seat with accommodations near home for the next administration date.
That 780 English is too good to leave out of her applications. She has a good shot at any school, with her excellent GPA, ECs, and underrepresented minority, first to college status. Did she take an AP math test? If she got a high score on an AP math test, she can submit it, and it can stand in the place of that low SAT math score. I would have her register for the November test, and then ask College Board to find her a site closer, WITH ACCOMMODATIONS of course! She might have a better score then to submit for regular applications, plus the results might be back in time to add to her ED/EA application, which probably has a Nov 1 or Nov 15 deadline, but they will accept test scores that arrive later.
If none of that comes to pass, I would still recommend submitting that first SAT to any school, because of that stellar English score. She wants to be a history major. With the strength of the rest of her application, I think that schools will overlook that low math score.
