This is a bit of code I hacked up once upon a time that did this: 

sub SuggestionSort {
    my ($toSort, $Suggestion) = @_;
    my (%sugg, $i, @sorted);
    foreach (@{$Suggestion}) { $sugg{$_} = $i++ };
    foreach (@{$toSort}) {
    if (defined $sugg{$_}) { $sorted[$sugg{$_}] = $_ }
    else { $sorted[$i++] = $_ }
    }
    grep defined, @sorted;
}

You would call it this way: 
use strict;

my @order = qw(whale elephant dog cat);
my @sortme = qw(foo bar baz cat dog elephant bird);

print join(", ", &SuggestionSort(\@sortme, \@order)),"\n";
