Currently, Sigil meets the 3.01 spec. The IDPF has disolved and merged with W3C. They have no spec. They are planning a completely new packaged web content spec for epub4 which does not even use an opf, or zip, or ...
An epub community within w3c has decided epub 3.1 is dead on arrival. They are trying to salvage an epub 3.2 or epub 3.0.2 that does not support any series meta either.
Once the calibre namespace prefix is added to the metadata tag, using calibre: metadata is completely legal for xml and use in an opf. The issue is adoption by readers but since there is no other viable solution ....
So do not hold your breath. Simply add the calibre namespace to the metadata tag in the opf and use your clip as the epub format is in for a very rocky future.
ie. Inside the metadata tag, my guess is adding the following attribute will do the trick, unless calibre has a more specific url that describes its metadata.
Code:
xmlns:calibre="http://calibre-ebook.com"
What does Calibre itself put in the metadata tag?

It would be nice though, if TPTB ever agree on a standard meta for series/# for that to be added to the meta editor in Sigil.
