The alternative is just specifying the value on each item. These two are equivalent:

  <ol reversed>
    <li>Three
    <li>Two
    <li>One
  </ol>

  <ol>
    <li value=3>Three
    <li value=2>Two
    <li value=1>One
  </ol>

Note also that reversing content via CSS is generally unwise, because things like screen readers, text selection and tab indexing operate on DOM tree order.
