Nope, he is not.
An unlabeled tape is the last one in the flowchart. And only iff "auto media 
management" is enabled.

The selection steps for a backup are: 

1. Appendable mounted tape in required Pool
2. Appendable unmounted tape in required Pool
3. Recyclable tape in required Pool
4. Recyclable tape in other Pool (with suitable "Recycle to" and "Recycle from" 
5. Unlabeled tape if "Auto media management" is turned on

Haven't tested all of those, but this is what the documentation says. 

And the point 5 is definitely last.
Just thought that it for some reason might behave differently on VTL as the 
"Virtual" also triggers
other different behaviour.
