I may be misunderstanding your problem, but the predicate probe_sched/5
expects a list of variables, so you can't give it a single variable 
which represents a list which is intended to be
later constructed dynamically:

probe_sched(
    + Starts,        
    + Durations,
    + Resources,
    ++MaxResource,
    ? CostFunction
        )

Starts:       List of integers or ic variables (Task start times)
Durations:    List of integers or ic variables (Task durations)
Resources:    List of integers or ic variables (Task resource consumption)
MaxResource:  Integer - maximum available resource
CostFunction: Expression in terms of task start times and durations,
              to be minimised.

    Cheers
        Mark
