I think this depends on the network. Most major tier 1 public IP backbones do not necessarily run QoS through the core. MPLS in these networks is used for traffic engineering such as constraint-based routing and dynamic LSPs. Private MPLS-based networks may (and do) use dynamic QoS signaling. Maybe someone who maintains one of these networks could chime in.
