I am not sure the function signature is correct above. In my tests, the function's first argument simply contains the name of the form, whilst the second, currently not shown in the above example, contains the form array itself. I believe it should be more like:

<?php
function filter_form_validate($form_name, $form) {
  // Do stuff here. $form contains the form array and we can use element_children() on it if we need to.
}
?>
