The betas of Acorn 2.1 now have support for AppleScript. You can grab a test version of Acorn 2.1 from the latest builds page. I also have some AppleScript samples up in the documentation.

If you're one of the folks who has been wanting AppleScript support in Acorn, like really really badly OMG I'll kill if I don't get it HERE TAKE MY FIRST BORN ER I MEAN HOW ABOUT THIS TASTY CARROT I SHOULD HAVE TRIED THAT FIRST, I'd appreciate it if you took a look at the dictionary, try it out a bit, and then sent me some feedback if you have any. I still can't seem to read people's minds; so if there's a feature you'd like to see, let me know.

Also, check out Script Debugger if you do any serious AppleScripting. It's pretty nice.
