"Feature Supported" isn't well defined here. jQuery Mobile's persistant footers are anything but persistant on iOS. That's a big feature for most UIs, and something Sencha Touch got right a long time ago. That poor support for viewport manipulations is lost in the rankings.
Instead of a Green/Orange/Red score for each platform, I think a letter grade or percentage of supported features would be better. Someone who hasn't developed with jQuery Mobile will think that since it has a green ranking for iOS, that they'll actually be able to make things that look like iOS apps. They won't (although iOS 5 should fix that issue).
We need a mobile framework that focuses on compatibility first and features second. Not a million clones of, "We can make HTML elements look like a shitty iOS!"
Most of these aren't frameworks. They are libraries of interface widgets that barely work.
The lack of MonoTouch/MonoDroid is the first thing that I noticed. While c# may not be everyone's cup of tea, it can be used to develop across iOS/Android/WP
