Sort Object Containing Multiple Arrays: JavaScript [duplicate]

Emm..I have a sample example, which having Object with Arrays,

Lets Consider

obj = {
 code:[1001, 1002, 1003, 1004, ..etc],
 name:['John', 'Kerry', 'Stepen', 'Mery', ..etc],
 priority:[20, 40, 10, 30, ..etc] //containing more than 10000 elements in an array
}

Expected Output:

obj = {
 code:[1003, 1001, 1004, 1002, ..etc],
 name:['Stepen', 'John', 'Mery', 'Kerry', ..etc],
 priority:[10, 20, 30, 40, ..etc] //Sort on Priority basis
}

Could any one have simple & faster way of sorting for this kind of pattern?

Thanks & Regards Niks
