I think it would definitely be useful to have an (optional) IV field in the COSE_Key structure. 

If it is not defined in COSE, it could still be defined by the application, as I assume you mean by writing:
* label => values
in COSE_Key CDDL definition.
If it is the case, I think there should be some text specifying that the application can define more fields. If it isn't and I interpreted the CDDL wrong, then I am strongly in favor of defining the IV field in COSE_Key, and removing (or explaining) that line of the CDDL COSE_Key structure.
