title: How can I sort by multiple conditions with different orders?
body: <p>I'd really like to handle this without monkey-patching but I haven't been able to find another option yet.</p>
  
  <p>I have an array (in Ruby) that I need to sort by multiple conditions.  I know how to use the sort method and I've used the trick on sorting using an array of options to sort by multiple conditions.  However, in this case I need the first condition to sort ascending and the second to sort descending.  For example:</p>
  
  <pre><code>ordered_list = [[1, 2], [1, 1], [2, 1]]
  </code></pre>
  
  <p>Any suggestions?</p>
  
  <p>Edit:  Just realized I should mention that I can't easily compare the first and second values (I'm actually working with object attributes here).  So for a simple example it's more like:</p>
  
  <pre><code>ordered_list = [[1, "b"], [1, "a"], [2, "a"]]
  </code></pre>
