I think the red badge that appears on the OmniFocus icon when OmniFocus is not running is a standard iPhone count display widget. It looks like the same one Mail uses. Since OmniFocus isn't running when you're looking at your iPhone's home screen, I'm not sure it can display anything other than the system-provided widget (which happens to always be read, regardless of what OmniFocus might want).
