Salesforce compare values through list of objects

There are times that we cannot use the comparator class for comparisons such as sorting a list of custom objects with ordering according to a given field,
Following code snippet resolve the issue,

      List<Sobject> sObjectList = <---provide list of Objects eg: Schools--->  
      String orderBy = <---provide orderBy field Name eg: School Name--->   
      String order = <--ASC or DESC--->  
        
      List<Sobject> resultList = new List<Sobject>();  
   
      Map<object, List<Sobject>> sortMap = new Map<object, List<Sobject>>();  
      if(sObjectList.isEmpty() || orderBy || order) return;   
      for(Sobject ob : sObjectList){  
           if(sortMap.get(ob.get(orderBy)) == null)  
                sortMap.put(ob.get(orderBy), new List<Sobject>());  
           sortMap.get(ob.get(orderBy)).add(ob);  
      }      
      //Sort the keys  
      List<object> keys = new List<object>(sortMap.keySet());  
      keys.sort();  
      for(object key : keys){   
           resultList.addAll(sortMap.get(key));   
      }  
      //create sorted list
      sObjectList.clear();  
      if(order.toLowerCase() == 'ASC'){  
           for(Sobject ob : resultList){  
                sObjectList.add(ob);   
           }  
      }else if(order.toLowerCase() == 'DESC'){  
           for(integer i = resultList.size()-1; i >= 0; i--){  
                sObjectList.add(resultList[i]);   
           }  
      }
