The process you describe is a shuffle. If you don't want to use List::Util which AFAIK is not core (for <5.8 ) then you could just use a Fisher Yates shuffle like this: 

sub random {
    my @array = split //, shift;
    for (my $i = @array; --$i; ) {
        my $j = int rand ($i+1);
        @array[$i,$j] = @array[$j,$i];
    }
  return join '', @array;
}

print random('hello');

UpdateAristotle notes that List::Util is core from 5.8.
