I have a negative reaction when you give wrong infos.
WordService behave flawlessly when installed correctly on a clean system.
The fact that it doesn't on yours just prove that something is wrong on yours.
I'm not in front of your machine (I have no info about it) but clearly something is wrong on it.

Macintosh HD:Library:Services:WordService.service:
I wish to add that Lion was installed on a blank HD, not upon an existing 10.6.8 system and that I run the apps from the iWork package, not those from Mac App Store.
Don't describe a wrong behavior as a general one before checking that it really strike elsewhere.
Don't worry, I behaved like you in the past. Now, I try to be more cautious.
For instance, when I wrote about an annoying behaviour striking upon dates in my system, I didn't stated that the system was wrong. In fact, it was just corrupted on my machine.
A bit of cleaning and the standard behavior was back.
