Alternatives to sortedArrayUsingSelector ?

All,
I fetch data from DB which is sorted in a particular order. I display this data using Array Controller in a table.
Since I execute the following statement

tell theArray to set my theData to sortedArrayUsingSelector_("localizedStandardCompare:")

the actual sorting is lost. What alternative selector or method is available so that the initial data sorting is maintained ?

SOLVED:
tell theArray to set my theData to theArray … DUH
