its the scaled score and not the percentile that counts, so dont fret.
However, I do think that the percentile matters more than the scaled score. Scaled scores wander all over the place; it's the percentile that's supposed to mean something year after year.
Admissions people pick whoever they like the best among the applicants that apply. So far as judging GRE scores, it doesn't matter whether they look at percentiles or scaled scores (or Ln(percentile * scaled score)/7.43 or any strictly increasing function of the scores) when comparing you to other people... the effect will be the same.
The scaled score is supposed to be an objective measure of performance independent of what version of the test was taken, what year it was taken and the performance of the other students who took it. I don't know how they come up with it statistically, but it still has information that the percentile doesn't as far as comparing the performance of test takers over the years. But that's not really relevant for the current group of applicants, who all took the test recently. The percentiles, OTOH, are updated every year to represent the recent test takers.
