If you write all INSERTs from a single node, yes, but because sharding is 
where each node has its own cluster within a Class, that wouldn't be the 
case if you INSERT on different nodes:  

ie.  INSERT on Node1:   adds   MyClass_Node1, @rid = #17:236
      INSERT on Node2:   adds  MyClass_Node2, @rid = #18:54
      INSERT on Node3:   adds  MyClass_Node3, @rid = #19:7632

so they are all MyClass, but different clusters, with a different high @rid 
which you can't use for sorting over the entire class.

One possible workaround might be simply to always try writing to the 
default cluster for a class directly, but I think there may be limitations 
on that right now.
