Column sorting doesn't alter the model, so there wouldn't be an annotation to control this behavior. It is best thought of as a search mechanism. Maybe someone who is authoring the list of instructions wants to see all "put" instructions together to check them for wording consistency. Something like that.
There is currently no means to disable column sorting in the list property editor. If you think that being able to do this would be useful in your scenarios, go ahead and open an enhancement request. We can add means to control this in sdef.
