That should be %s have %s message%s left'. Using %d in perl is rarely the right thing to do: 
$ perl -we'printf qq[%d\n], 3e9'
3000000000
$ ssh shaggy "perl -we'printf qq[%d\n], 3e9'"

%d is a C concept, and doesn't map well to Perl's pick-one-of-three possible formats to store a number.

%e/%f/%g are also not completely problem free, since they could end up losing precision on a 64 bit int/53 bit mantissa perl.
