This works, and I like that it uses as few explicit variables as I can manage while still chomping.

use v5.10;

say for sort { $a <=> $b }
  map { chomp( my $i = <> ); $i } 1 .. <>;

Since it's just a throwaway, I suppose you could even rely on Perl's numification rules, eliminating chomp, and thus further eliminating the use of variables, making it as pure a "filter" as possible:

print for sort { $a <=> $b }
  map { scalar <> } 1 .. <>;

I also kind of liked this one, but it's more verbose: 

my $count = <>;
my @numbers;
while( $count-- ) {
  push @numbers, scalar <>;
}
print for sort { $a <=> $b } @numbers;
