Customize order of a list in Drupal 6
In your own custom module implement hook_views_pre_render and alter the view's result in the following manner:

function MYMODULE_views_pre_render(&amp;$view) {
  if ($view-&gt;name == 'my_view') {
    // for example reverse the result
    $view-&gt;result = array_reverse($view-&gt;result);
  }
}


Use devel module and namely the dpm function to test your code before and after. It is very handy.
Hope this helps.
