title: open office sort - month and year
body: <p>I just want to sort this based on Month and year combination (that is, based on column A) ascending. How to do this in OpenOffice Calc? The sort option on month is not working because I guess the year is also appended.</p>
  
  <p>Here are some data starting from A1:</p>
  
  <pre><code>Month                    Total
  September 2011           27825
  September 2010           35801
  October 2011             108485
  October 2010             22223
  November 2011            139222
  May 2012                 39319
  May 2011                 38226
  May 2010                 9671
