[PE-D][Tester D] Schedule based on priority

[nus-se-script]

Let's say I want to add schedules based on clients' priority, from top priority to low priority. After I have sorted the list,

And scheduled the first person Roy, the sorted list is gone.

Suggestion: It would be more optimised if the sorted list remains so users don't need to keep sorting the list every time.
