title: Sorting names by their high scores
body: <p>I want to sort a list of names by their score.
  What I have so far is</p>
  
  <pre><code>file = open("scores.txt", 'r')
  for line in file:
      name = line.strip()
      print(name)
  file.close()
  </code></pre>
  
  <p>I'm unsure how to sort them.</p>
  
  <p>Here's the file contents:</p>
  
  <pre><code>Matthew, 13
  Luke, 6
  John, 3
  Bobba, 4
  </code></pre>
  
  <p>What I want the output to be:</p>
  
  <pre><code>John 3
  Bobba 4
  Luke 6
  Matthew 13
  </code></pre>
  
  <p>Can anyone help?</p>
