There is not a problem with subinterfaces on 7604 as long as you use them in consistent ways. But you are trying to use them in inconsistent ways. When you configure the subinterface on the 7604 you are setting it up to process as a trunk. But on the switch you have configured the port as an access port and not as a trunk port.
Your point is well taken that It seems like the sub-interface dot1q 50 is not matching up with the 3750 vlan 50. It is not matching because one end is trying to trunk and the other end is trying to access.
You resolve this difficulty either by configuring the interface on the 7604 as access not trunk (by removing the subinterface and configuring on the physical interface) or you fix it by configuring the interface on the switch as a trunk port.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
