If you don't want to use the transform, you can always sort multiple arrays by the order of one: 

my @ids;
my @titles;
my @dates;

foreach $line (@FILE) {
    my($id_number, $title, $date) = split(/\|/,$line);
    push (@ids, $id_number);
    push (@titles, $title);
    push (@dates, $date);
}

my @sorted = sort { $titles[$a] cmp $titles[$b] } (0 .. $#titles);
@ids    = @ids[@sorted];
@titles = @titles[@sorted];
@dates  = @dates[@sorted];

Not quite as elegant looking as the Schwartzian Transform, but it will do the trick. Also, this will be easier to work with if you need to modify $title, $id_number, or $date in the foreach loop.
