I want to sort a singly linked list in a descending order , I made a function but it doesn't seem to be working

This is my whole code I made a function to add to head and a function to print the whole list and a function to sort the list in a descending order. There is no error whenever I run the code and the linked lists doesn't rearrange in a descending order it prints out the same order

#include <iostream>
using namespace std;
#include <string.h>

class Node{
public:
    string data;
    Node* next , *head; 
    int counter=0;
};
class tsortedList :public Node{
public:

void printlist(){
    Node *t = head; 
    while (t != NULL){
            cout<<t->data<<", ";
            t = t->next;
        }   
}
void insert_at_beginning(string data){
            Node *temp = new Node();
            temp->data = data;
            temp->next = head;
            head = temp;
            counter++;
        }       
void Sort(){
        Node* temp;
        temp = head ; 
        string info ;
        for (int j = 0; j < counter; j++)
        {

            while ((temp->data) < (temp->next->data)  ) 
            {


                info=temp->data;
                temp->data = temp->next->data; 
                temp->next->data=info;
                temp = temp->next ; 
            }

            temp = temp->next ; 

        }
        temp = head ;
    }        
};
int main(){
    tsortedList obj;
    obj.insert_at_beginning("Apple");
    obj.insert_at_beginning("bannana");
    obj.insert_at_beginning("Zebra");
    obj.insert_at_beginning("Horse");
    obj.printlist();
    obj.Sort();
    obj.printlist();
