Here's one that is 65 characters, returns as array of arrays, but has duplicates (though the orders are unique).
sub P {
$_[0]?map{my$c=$_;map[$c,@$_],P($_[0]-$c)}(1..$_[0]):[]
}
Update: Same thing, but avoids repetitions: Total
chars: 96
sub P {
my$b=$_[1]||$_[0];
$_[0]?map{my$c=$_;map[$c,@$_],P($_[0]-$c,$c)}grep{$_<=$b}(1..$_[0]):[]
}
