Sorry, that got sent before I was done editing it.

Is there a problem when one item has publisheddate and another only has
enumchron? I still don't really understand enumchron, but I think we want a
failover between two sets of comparisons, not two failovers of criteria.
That is, unless I misunderstand and publisheddate and enumchron really are
interchangeable to that degree. Can you confirm, Ryan?
Otherwise I would propose something like :
sub sort_pubdate {
my $key = 'publisheddate';
$b->{$key} and $a->{$key} or return 0;
$b->{$key} cmp $a->{$key};
}
sub sort_enum {
my $key = 'enumchron';
$b->{$key} and $a->{$key} or return 0;
$b->{$key} cmp $a->{$key};
}
sub sort_either {
($b->{publisheddate} || $b->{enumchron})
cmp
($a->{publisheddate} || $a->{enumchron}) ;
}
...
return( sort {&sort_pubdate || &sort_enum || &sort_either } @results );
