what's so painful about:

GList *list = gtk_container_get_children (GTK_CONTAINER (box));
gint   pos  = g_list_length (list) - 1;

for (; list; list = list->next, pos--)
  gtk_box_reorder_child (GTK_BOX (box), list->data, pos);

I haven't tried this, but unless I am mistaken this should reverse the
order of children in a box. Seems easy enough to do and avoids the need
to introduce yet another special case in the GtkBox code. Perhaps if
this solution is not obvious enough, this should be turned into a
utility function gtk_box_reverse_children_order() ?
