sure you can:
function(keys, values) {
var sorted = sort(values);
return [values[0], values[1], values[2], values[3], values[4]];
}
the above really really simplistic reduce demonstrates that you can return
sorted subsets of a value for a given key.
With a little key inspection you can deterministically return subsets for
only certain key types.
