Sorting gameobjects using sorting algorithms

I want to sort 5 spheres in Unity by using sorting algorithms. They will swap places in sorted order after I click sort button. I manage to create a list for gameobjects but as I understand it is only sorting the list then do nothing. How to create such script that I want? It will swap objects by gameobject name. The Envrioment, the code that I made so far;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using UnityEngine;
using UnityEngine.UI;

namespace Assets
{

    class Gameobjects : MonoBehaviour
    {
        public Button s_YourButton;
        [SerializeField]
        private GameObject[] deck;

        public List<GameObject> instanciatedObjects;

        void Start()
        {
            Button btn = s_YourButton.GetComponent<Button>();
            //Calls the TaskOnClick method when you click the Button
            btn.onClick.AddListener(TaskOnClick);

        }

        void TaskOnClick()
        {
            Fill();
            instanciatedObjects = instanciatedObjects.OrderBy(Sphere => Sphere.name).ToList();
        }

        public void Fill()
        {
            instanciatedObjects = new List<GameObject>();
            for (int i = 0; i < deck.Length; i++)
            {
                instanciatedObjects.Add(Instantiate(deck[i]) as GameObject);
            }
        }
    }
}

Any idea is welcome for me to do futher research, I am new to Unity.

First you can do is store a list of Vector3 of the old one. basicly List.Add(spawnedObject.transform.position); inside the for loop in Fill().

Then after you sorted them, you loop the instanciatedObjects and set them in the same order as the Vector3 list.

List<Vector3> vectorList = new List<Vector3>();
void TaskOnClick()
{
    Fill();
    instantiatedObjects = instantiatedObjects.OrderBy(Sphere => Sphere.name).ToList();
    for(int i = 0; i < instanciatedObjects.Count; i++)
    {
        instantiatedObjects[i].transform.position = vectorList[i];
    }
}

public void Fill()
{
    vectorList.Clear();
    instantiatedObjects = new List<GameObject>();
    for (int i = 0; i < deck.Length; i++)
    {
        GameObject spawnedObject = Instantiate(deck[i]) as GameObject;
        instantiatedObjects.Add(spawnedObject);
        vectorList.Add(spawnedObject.transform.position);
    }
}

btw, a typo in your code: instanciatedObjects should be instantiatedObjects
