title: MySql values do not arranged by proper value
body: <p>I have a Mysql table,
  I want to sort the values in the table by size of the <code>meta_value</code> from biggest to smallest. </p>
  
  <p>Look at the order of the value? 
  How come <code>150,000,000</code> is smaller than <code>1,555,555</code> .</p>
