We have created a consolidated wiki page that discusses various strategies for integrating AppleScript with Indigo and we highly recommend that you read through those options (particularly in light of the AppleScript to Indigo Server deprecation in Indigo 7.4). That wiki page is in the developer section which means that anyone with write access to that section of the wiki can add things as well as new integration methods come up.
Let us know if you have some ideas for that page and we'll add you to the editor list.
