A 2230 on the old SAT is a great SAT score , but if you're applying to some of the most selective schools in the country, then it might be worth it to retake (particularly to improve your Reading score).
While it's unlikely that colleges will formally superscore between the old and new SAT, that doesn't mean that they won't look at your scores on both the old and new SAT and compare them. A direct comparison between the tests isn't possible because the tests cover different materials, but a 700+ Evidence Based Reading and Writing score on the new SAT will offset a 690 on the Critical Reading section of the old SAT.
