Same issue as well...trying to troubleshoot but haven't had much success.
UPDATE:
Looks like the "parse tasks with transport text" script is not working with latest beta drop from Omnifocus.
I replaced "parse tasks with transport text q" with "make new inbox task with properties {name:q}" which creates a simple inbox tasks for now (until they fix the issue)
Here is the Applscript, just copy/paste into the script editor.
on alfred_script(q)
set theName to (q)
set isRunning to false
tell application "System Events"
if exists process "OmniFocus" then
set isRunning
