>From the docs [1] it appears that values should actually be an array
reference so maybe the following would work:
$html .= $cgi->popup_menu(
-name => 'id',
-values => [ sort keys %terms ],
-labels => \%terms
);
It just creates an anonymous array of sorted keys from the terms hash. The
labels option is used to show the term names rather than the IDs in the
menu.
I haven't actually tested it, but give it a shot (see the docs for more
info)
