Sorry, I am not sure if I understood your question properly. There would be no
expression involved in my suggestion.
legCtrl1.fkik would simply be a boolean 0 or 1 type.
You create the scriptJob completely outside of that property. The scriptJob
simply says "run this code when this attribute changes values".
Now you don't have to pass it a callable object. You could have passed it
python strings:
###
jobId = cmds.scriptJob(attributeChange=['legCtrl1.fkik', """
val = cmds.getAttr('legCtrl1.fkik')
if val == 0:
cmds.setAttr('legCtrl1.tx', k=False)
elif val == 1:
cmds.setAttr('legCtrl1.tx', k=True)
"""])
###
Because you are working with the python commands module, the commands expect
python code, not MEL procs.

The documentation for scriptJob is here:

You would not be using expressions (from my example). You would be passing
callable functions.
