A number of years ago, I modified the 'largest20' script created by Randal Schwartz for my purposes. It's easy enough to tweak it to do what you want:
#!/usr/bin/perl -w
use File::Find;
die "$0 <count> [dir]\n" unless @ARGV >= 1;
my %size;
my $count = $ARGV[0];
my $search = $ARGV[1] || $ENV{PWD};
find (sub {$size{$File::Find::name} = -s if -f;}, $search);
my @sorted = sort {$size{$b} <=> $size{$a}} keys %size;
splice @sorted, $count if @sorted > $count;
printf "%10d %s\n", $size{$_}, $_ for @sorted
