Patrick,
    What I am trying in the following step does work:

1) I define a local jython function:
#
def pointPressure(ALTI, Altitude):
    return (ALTI * ((288 - 0.0065 * Altitude)/288)**5.2561)*33.8639

2) in the layout model editor, I am changing the upper right corner value 
symbol, in the Value parameter box, I enter pointPressure(ALTI, Altitude), and 
the Unit box "Millibars", and so on..

3) save the layout model

And I see no problem display the value, even though I am not sure if the value 
is corrected or not.

Give it a try.
