IPC::Cmd's command option takes one string or array reference that specifies your command. Since you have a pipe "|" in your command(s), you are stuck with specifying a string. Or you can try IPC::Run 
use IPC::Run qw(run);

my @in = ("Test foo", "Test bar");

run [echo => -n => @in] , '|', [ sed => "s/(foo|bar)/pass/" ], '>', \m
+y $out;
