Wrong sort order - primary links

I just tested this (great ;) module, I took primary links into it and the order of the items was wrong. So I searched a little and found, that the menu_links.weight and menu_links.plid had no value (there was no changing weight action, I simple added them one by one). So, I think, it would be right to have "ml.mlid" in the "order by" clause (in footermap_get_menu) - it worked for me.
