doh- I guess I'm duplicating some work then! hahaha. I'll have to check out the scripts! Here's an idea of what I was playing with recently:

tell application "OmniFocus"
	tell front document
		tell document window 1
			set theSelectedItems to selected trees of content
		end tell
		if ((count of theSelectedItems) = 1) then
			set selectedItem to value of item 1 of theSelectedItems
			set selectedNote to note of selectedItem
			if selectedNote contains "&Q2" then
				display alert "Project already is a Q2 project."
			else
				display alert "I will now make this project Q2"
				set newNote to "&Q2: Covey Q2 Task" & return & selectedNote
				set note of selectedItem to newNote
			end if
			return
		end if
	end tell
end tell

Very simple, but it may give you some ideas...
