I'm no expert.., but seems like maybe your radio group isn't the same for your 3 gtk_radio_menu_item_new_with_mnemonic calls, otherwise Gtk handles toggling of the radio buttons for you.
Note, to prevent your callback being triggered when you call gtk_check_menu_item_set_active, you can use g_signal_handlers_block_by_func or one of its variants.
