Ah, I see.  Well then, you can use either method to obtain the count:

  # a -- from perlfaq4
  my $prev = "NO_SUCH_VALUE";
  my $dup = 0;
  my @sorted = grep { $_ ne $prev ? $prev = $_ : ++$dup } sort @records;

  # b -- also from perlfaq4
  my %seen;
  my @sorted = sort grep { !$seen{$_}++ or ++$dup } @records;


I'd probably go with a) though, for the following reasons:

  1. you said you want to sort everything anyway
  2. we don't need to use a hash
