title: Wikipedia API returning sorted data instead of random data
body: <p>I am trying to generate random articles from a category using the Wikipedia API sandbox. <br> <br></p>
  
  <p><a href="http://en.wikipedia.org/w/api.php?action=query&amp;list=random&amp;format=jsonfm&amp;rnnamespace=0&amp;generator=categorymembers&amp;gcmtitle=Category%3ATeam%20sports&amp;gcmnamespace=0" rel="nofollow">http://en.wikipedia.org/w/api.php?action=query&amp;list=random&amp;format=jsonfm&amp;rnnamespace=0&amp;generator=categorymembers&amp;gcmtitle=Category%3ATeam%20sports&amp;gcmnamespace=0</a></p>
  
  <p>But whenever the query is made articles were returned in alphabetical order rather than randomly. <strong>Also the same set of articles is returned each time</strong>. The number of articles retrieved each time is much lower than the total number of articles in the category. What is the bug in the query?</p>
