Cube Sorter

Ok so in my scene, I have an empty game object called CubeMaster.

Inside are 5 cubes. Each cube is in a line, but their order on scale is mixed up.

My goal is to sort them all with a click of a button.

I am using the BubbleSort algorithim for this task.

I made a script called SortObjects. This is what it looks like:

 public class SortObjects : MonoBehaviour
 {
     public GameObject cubeParent;
     private GameObject[] CubesToSort;
 
     public void onClick()
     {
         CubesToSort = new GameObject[cubeParent.transform.childCount];
 
         for (int i = 0; i < cubeParent.transform.childCount; i++)
         {
             CubesToSort[i] = cubeParent.transform.GetChild(i).gameObject;
         }
         BubbleSort(CubesToSort);
 
 
     }
 
     private void BubbleSort(GameObject[] A)
     {
         int i; 
         int j; 
         Vector3 temp; 
 
         for (i = (A.Length - 1); i >= 0; i--) 
         {
             for (j = 1; j <= i; j++)
             {
                
                 if((A[j - 1].transform.localScale.sqrMagnitude) > (A[j].transform.localScale.sqrMagnitude))
                 {
                     temp = A[j - 1].transform.position;
                     A[j - 1].transform.position = A[j].transform.position;
                     A[j].transform.position = temp;
                 } // end if
 
             } // end for 2
 
         } //end for 1
     }
 }

Basically what it does is checks if the cube to its right is bigger, then they are flipped around. This process is repeated until they are sorted. Unfortunately when I press my button, it looks like this:

Did I do something wrong?
