Your $a=<STDIN> leaves $a containing for instance "5\n", that is, including the newline.

If you just chomp($a) your code would work. Unless there were trailing spaces or stuff ...

Better to use $a+=0; to make it numeric.

Oh, and as the monks are sure to be telling you: You should not use $a outside of sort, since that is a special variable there.
