I think the uname(1) command-line arguments should be considered as on-off switches, not as formatting specifiers: you can only instruct uname(1) whether to display or not the specific characteristics, but the order is hardcoded. Are there any OS's where the uname(1) output is really dependent on the order of the command-line options? A couple of quick tests with several flavors of Linux showed the same behavior there...
