Part of the slowness here is probably that OmniFocus is very aggressive about preserving your data. Each modifying change invoked via AppleScript saves to disk in a transaction, and this can make this quite slow if you are doing a ton of operations all at once.

You can turn this behavior off by setting 'will autosave' on the document to 'false'. Once you are done with your bulk import, you should turn it back on.

OmniFocus currently won't turn this back on for you, so if you leave it off, the user's document will get marked dirty and no changes will be saved in it until they close it.
