Hmm. Okay, my understanding of how the system associates apps might be incorrect. Lizard's suggestion should work, I was just hoping you could do it in a cleaner fashion.

Do you still have the old version of OmniFocus installed anywhere on your system?

By the way, you need to replace things like this:

-- Add waiting for context task to OmniFocus
				tell application "OmniFocus"

with

tell application id "com.omnigroup.omnifocus.macappstore"

There are some scripts that use

tell application id "com.omnigroup.omnifocus"

instead of

tell application "OmniFocus"

but either way, you need to change the tell application blocks to the form suggested by Lizard.
