If I hypothetically had not called the school to find out what a "typical" or average score was, and had no baseline for comparison of my score, I'd definitely retake it if I got anything less than 99. After all, in this hypothetical situation, I am asking random nurses on the internet who may have taken the TEAS 15 years ago, what score they got accepted with, even though I just took the brand-new TEAS 6. In this hypothetical situation, I have no idea what score will or not will be good, so I'll need to take the TEAS again in hopes of getting a better score, since I do not know what a good score is, only that I can get a better one.
If it were not a hypothetical situation, and I were actually living this situation, I would call the school and ask. No one on here has any clue what score will help you, since every school, every year, is different. Admissions will generally tell you a "typical range" of scores, what the "cutoff" score is, or something else that is useful. No one here can offer any advice that actually applies to you; only the school can.
