Well, they don't understand private vlans.
order to join the primary (downstream) and secondary (upstream) traffic. For that to work you would need to allow also the primary vlan on the Te1/1 trunk. You would not really need the "private-vlan trunk" feature, you can transport them on a normal trunk port (and join them on the access switch).
The "private-vlan trunk" feature is useful in a scenario where one port (Te1/x) belongs to one customer and you are handing over multiple secondary vlans over that port. This seems like is not your case. BTW I believe it is supported on latest CatOS...:)
Really? Because the IOS docs for Cat4500 imply that it is used when the downstream switch does not support private vlans:
