Problem is that the label, in my opinion, should not be changed since it 
is a user input.
My understanding is that this is a MARC::Record (MARC::File::USMARC) 
issue, I sent my script on perl4lib to detail the problem and explain 
what I have to do to fix that. But had no feedback.
Your solution could be a quick fix for display purposes.
But would not be right if you have to save the record since your label 
would not be UNIMARC but sort of UNIMARC21.

Anyhow the first problem addressed by the patch sent should not be 
forgotten though. Since it is really a problem for UNIMARC XSLT usage 
(see XSLT.pm modification).
