请教一下各位仁兄 ，下面代码如何才能用tlist.sort排序？

unit Unit1;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;

type
TForm1 = class(TForm)
Button1: TButton;
procedure Button1Click(Sender: TObject);
private

public

end;

var
Form1: TForm1;

implementation

{$R *.dfm}
procedure TForm1.Button1Click(Sender: TObject);
type
pmuo=^muo;
muo = record
muoname:string;
hsgs:integer;
end;

var
muoList: TList;
amuo:pmuo;

begin
muolist:=TList.Create;
New(amuo);
amuo.muoname:='d:\001.bmp';
amuo.hsgs:=3;
muolist.Add(amuo);

New(amuo);
amuo.muoname:='d:\002.bmp';
amuo.hsgs:=2;
muolist.Add(amuo);
end;

end.

现在想根据muolist各项的 的hsgs字段进行排序，我只知首muolist.sort() 可以实现，可是搞了半天还是一头雾水，请大侠们帮一下我啊，最好能写一点儿代码，万分感谢！
