Although making a checksum when tagging is fairly easy and darcs should
have an option to insert the hash in the tag description (or make it
the default).

I would guess that using the pristine hash for this purpose would be fine,
in this case this is as simple as :

darcs tag $(head -n 1 _darcs/hashed_inventory | cut -d: -f2)
