I think you may be talking about ordered label distribution vs. independent
label distribution
http://tools.ietf.org/html/rfc5036#section-2.6.1

<http://tools.ietf.org/html/rfc5036#section-2.6.1>Cisco's implementation is
independent where Juniper and maybe other vendors is ordered.
Cisco will advertise a label for everything in its routing table regardless
of how it learned it, where Juniper will only send a label for its connected
loopback and everything else it received that is *already* labeled from the
upstream.
There is ways you can ACL bindings in Cisco so it only sends labels for what
you need, but you can't change its implementation to ordered except for
cell-mode MPLS.

Rick,
I haven't done anything with CsC but,
are you sure there is one label per vrf?
I am asking since it looks like Cisco can keep stats per prefix that is
labeled, and the BPG labels on individual vrf routes are different:

This are coming from the same PE:
7200-UT01>sh bgp vpnv4 unicast vrf vrftest 10.3.0.0/16 | in labels
      mpls labels in/out nolabel/525
7200-UT01>sh bgp vpnv4 unicast vrf vrftest 10.1.0.0/16 | in labels
         mpls labels in/out nolabel/657
