Did you read RobTrew's excellent FAQ on installing and using scripts with OmniFocus in the OmniFocus Extras forum? There is a procedure given which will create the proper directory structure, if followed precisely. It boils down to turning on the AppleScript menu, switching to OmniFocus, then using the AppleScript menu to open the application script folder, which will create it if necessary. Placing your scripts in that folder is the best practice, and OmniFocus will allow you to add toolbar buttons to invoke scripts found there.

The only tricky bit about the procedure is that it works for any application, so if you accidentally switch to your web browser or the Finder by clicking in the wrong spot on the screen, you won't get any sort of error, you'll just make the application script folder for the application you were in when you did the open script folder menu command instead of for OmniFocus.
