Do they need to be prioritized? Best if not, but if you must then the 3rd parameter sets priority, with the default priority being 10. So to get Plugin One to fire AFTER Plugin Two use any number larger than 10:
add_action ("pre_user_query", "plugin_one_pre_user_query", 11);
add_action ("pre_user_query", "plugin_two_pre_user_query");
Of course plugins that must be loaded before others should be avoided whenever possible because multiple plugins might get the order wrong and it can be a mess, although sometimes setting priority can't be avoided.
Hope this helps.
