Update:
Okey-dokey. Just checked/spoke with Apple support. Senior advisor advises that he has also experienced this problem and that it's shown up on a number of discussion boards. Engineering is to be consulted for potential problem resolution — which likely means that it may be addressed in a subsequent OS 10.7 update.
In the interim I suspect that it's nothing to be concerned about, namely that TM is properly doing its business.

Okay, here's the 'final' skinny on the issue from the senior advisor who just got word from Apple's engineers:

It seems that this (not being able to verify) is normal behavior in Lion, unless backing up to a network drive. The "local" backups on Lion (which include USB external hard drives) verify automatically.
