Your problem is not Perl specific. The order by column
must be in the result set (projection). Why not doing
it this way:

my @fields = qw/name zip location/;
push @fields, $sort_selection;

$sqh = $dbh->prepare( "SELECT " . join(', ', @fields) .
" FROM company ORDER BY $sort_selction; );
$sqh->execute();
