Thanks Tones! Looks like I may have been overthinking this – just :filter, working backwards from the match found and seeing when you hit the current tiddler, is sufficient:
\define xcor-sort() [backlinks[]tag[Use]] :filter[links[]field:title<currentTiddler>] +[count[]] \define xcor-count() [<crossRef>backlinks[]tag[Use]] :filter[links[]field:title<currentTiddler>] +[count[]] ... <$list filter="[all[current]backlinks[]tag[Use]links[]!tag[Use]!field:title<currentTiddler>sort[]!sortsub<xcor-sort>]" variable="crossRef"> <$set name=numPaths filter=<<xcor-count>>> <li><$link to=<<crossRef>>/> (<$text text=<<numPaths>>/> occurrence(s))</li> </$set> </$list> (A different subfilter is needed for the sort than to populate the count variable in 5.2.3 since the tiddler being processed by a subfilter can't be retrieved through a variable. This could probably be tweaked in prerelease so you only need one subfilter.)
