Javascript array sort questions

Here is my delima ,that I hope some one can solve.Here goes.I have two arrays. lets say arr1 is my sort array in which I sort based on a critera and is one dimentional. Lets say it is a number sort.Ok I can do that and get it to return correct.Here is the problems arr1 is my sort field.My other array is an array of a single row data consisting of 7 fields. So the mock up is this.

arr1[0]=55;
arr[1]=45;
objArray[0]=JOHN DOE#HELLO#12/13/2004#&7:30:00 AM#45
objArr[1]=JOHN DOE#HELLO#12/13/2004#&7:30:00 AM#55

once arr1 is sorted I need the entier row(ObjArr) to be resorted according to values in arr1 to be added. Next question how do you sort time like that 7:30:00 AM format?
