QGSP_BERT_HP does not have a cut for neutrons since it would reduce its physics performances. Compare files QGSP_BERT.icc and QGSP_BERT_HP.icc located in source/physics_lists/lists/include/ (version 10)

In particular pay attention to the line (present only in QGSP_BERT) 
  // Neutron tracking cut
  this->RegisterPhysics( new G4NeutronTrackingCut(ver));

With the constructor mechanism, you can add this tracking cut also to QGSP_BERT_HP directly in the main function of your program:

int main(int,char**) {
    // ....
    G4VModularPhysicsList* myPL = new QGSP_BERT_HP;
    myPL->RegisterPhysics( new G4NeutronTrackingCut() );

Check the API here:

Both a time and energy limit can be set.
