When you use the -p commandline switch perl wrapps your code in
while (<>) {
} continue {
	print;
}


So what you en up with is
while (<>) {
	open...
        print ...<>
} continue {
	print;
}

What's happening is the <> operator on the sort line, sess EOF and stops
BUT the <> in the while loop never sess it.  AFAI concerend the file is open
just slow, so it blocks forever.
