First off, scores are always in increments of 10, so the difference isn't as great.
Secondly, in 2005, they changed the test from a two-section test to a three-section test. Each section is 800 points, so the old test had a total of 1600 but the new test has a total of 2400 possible points.
Scores are sometimes written as a total, sometimes as (for example) 800M-800V-800W [Math-Verbal-Writing], so that might make a difference in how someone displays their score.
Edit: general kill's score is 2010/2400 while Cheezy the Wiz's score is 1210/1600. That's why they look so different. 1210 used to be an okay score, but on the new test it would be terrible.
