I agree, if you're running OmniFocus all the time this script is useless, but on my machine OmniFocus isn't running all the time. Sometimes I really need to make a quick todo out of a random thought I had. Starting OmniFocus, waiting for it to be ready, sometimes takes to long and I simply (have) forgot my idea. So in the meanwhile I was using TextMate as a sort of temporary storage for those quick ideas.
Now I can throw a task into LaunchBar and let it handle the rest for me.
