I am not sure if this is a GDL question or more of a scheduling question.
So you have a parameter in your objects that your users can set and you are happy with that?
If so then it is a scheduling problem (and I will move this post).
You will need to add that parameter as a field in the schedule and then you can sort the order either ascending or descending as you wish.
