<p>I think you can rest assured, that admission officers are human enough to understand the possibility of making stupid mistakes during the test. I strongly doubt any admission rule exists that mechanically sorts out all those poor 790s.
Neither do I see how a 790 could possibly hurt you, nor why you would want to retake the test.
People with much lower test scores get accepted to the schools you mentioned. If you are a competitive applicant overall, no such score could destroy your chances.</p>
