The value of a standardized score over the raw score is knowing what percentile that score is in. This allows you to know what percent of test scores were above and below this value.

The example given here, shows that just knowing a raw score for the Verbal and Quantitative GRE is a bit misleading. The lower raw Verbal score has a higher standardized score (~92nd Percentile) than the quantitative (~77th percentile) even though the raw scores are showing the opposite. This is because the mean and the standard deviation are different for each sub-test.
