title: Sorting content of text file by number
body: <p>I have a text file that contain data like:</p>
  
  <blockquote>
    <p>12, abcd</p>
    
    <p>2541, sdfrhk</p>
    
    <p>4, qwerty</p>
    
    <p>13, uytrew</p>
    
    <p>345, iuoiyt</p>
  </blockquote>
  
  <p>How can I sort content by number in descending order? Preferably using batch. Thanks</p>
