Sort Array along with its Corresponding index

Hi,
  I have a one-d Array named zz containing {5,3,8,1,9,6}. Current order of indices of the elements is : 0,1,2,3,4,5. 
Now I want to sort the array z in ascending order in such a way that its corresponding indices also sort according to its respective elements.
Ex: Elts in Ascending order : 1,3,5,6,8,9
and Respective indices will be : 3,1,0,5,2,4.
Is there any readymade function available ? Hope the question is clear..Kindly provide the solution on urgent basis.



Thanks in Advance,
