Craig, No, right now OpenVPN (and I believe the Linux TUN driver as well) has no special handling for QoS such as TOS pass through between different encapsulation layers (though it's an interesting idea).
You could, of course, apply QoS rules to OpenVPN's UDP connection or make use of OpenVPN's traffic shaping option (--shaper) for basic control over output speed. By using multiple tunnels between the same hosts, each with different QoS rules, you could accomplish some of the same effect.
