Hmmm. That's weird...

The distinction between 'Z' and '1' at transistor level can only be made in a test bench that loads the output. For instance, a small current-source load would start to pull a 'Z' state down while a '1' state stays up. By detecting the onset of the pulldown for a '1'-to-'Z' or the onset of a pullup for a 'Z'-to-'1' you can determine the wake-up time. If you do this for two or three values of the load current, you should be able to determine the wake-up time and its dependency in the load (or fan-out).
That's how I would approach the problem, at least. I think you can capture this in .measure statements without a problem.
