The review groups are already sorted with 5's at the top. I think it's fine as it is. the exact dollar amount and quantity is only listed for new reviews. This is not new info because anyone scraping the site before could get this info as reviews rolled in. Now everyone has it. Additionally, because only transactions that have a review written for them are displayed, you can't get a complete picture of a vendor's business like you used to. In my opinion, that alone makes all of the headache of this change worth it.
