I think that Davidson will adjust their WISC V criteria if they find that scores are coming in low (criteria are periodically adjusted, it seems). They seem to have very specific things that they are looking for with each individual test, though, as I would have to guess that they see many, many scores. I seem to recall that the same concerns were expressed over the WISC IV and WPPSI IV when they first came out. I simply cannot comment on how they would interpret her scores, as our situation was different. Perhaps someone here who has applied more recently has better insight. The good news is - you only need to qualify on one test, and the WISC V is not the only test available. If she took the EXPLORE or SBV (or any of the other listed tests) and the scores qualified, my understanding is that you would not need to submit anything additional.
