Without access to the model, I can only vaguely speculate what the issue is here... CT has some pretty subtle ways of handling simultaneous events (which are legitimate at discontinuities and to represent glitches). The AddSubtract actor has distinctly different semantics from the Expression actor in that it does not require all inputs to be present to fire, but I doubt that would affect the CT schedule unless there is a truly subtle glitch or race condition in the model...

Offhand, I'm not sure, so I'm forwarding this on to Ptolemy-Hackers.
