Can you share your script?

I'm using the same technique but there is a problem with tape expiration.
When you expire all images of one tape the tape doesn?t expire. 
You have to search for assigned tapes that they don't have media and then you 
have to use the bpexpdate - jusmedia command to expire the tape.
