Taking MCAT after a sudden interview invite

Someone I know has planned to retake the MCAT in just over a week. She just received her first interview invite this evening from a Texas school. She's a texan. Should she defer the retake to a later date?( in the case she does get accepted, she can cancel the MCAT) Or... Should she take the MCAT in January anyway and hope for a higher score?
