Thanks a lot. I finally use link_alter (see below)

I was wrong.
It's possible to add a 'class' attribute to links, and taxonomy links come all together, so it's possible to reorder if wanted.

the solution I took :

function edulibre_link_alter(&$links, $node) {
  // we just want to alter taxonomy terms
  if (strpos(key($links), 'taxonomy_term_') !== FALSE) {
    // our vocabularies specific css classes
    $classes = array(
      VID_KEYWORDS => 'keywords',
      VID_TYPE => 'type',
      VID_LEVEL => 'level',
      VID_SUBJECT => 'subject',
    );
    foreach ($links as $key => &$link) {
    	$link['attributes']['class'] = $classes[$node->taxonomy[substr($key, 14)]->vid];
    }
  }
}

I don't play with order here, because I saw it's enough to change vocabularies order in admin/content/taxonomy.
