The only alternative that comes to mind is
count(xx:intersection($nodeset, preceding::node()))

where xx:intersection can be done either using an extension function or

But your method is probably faster!

(The other approach is to ask whether you couldn't have determined/retained
the position at the time the node-set was being built in the first place).

It certainly would make sense for XPath to provide a node-identity test;
whether it would have been better to use the "=" operator for that purpose
is an unanswerable question.
