Multisite activation plugin fails on additional blogs (missing column)

Thank you for the plugin (and I’m sorry to bother you again ?? I’m not really a developers stalker).
The plugin activation function is not “network compliant”.
The SQL is done only for first blog. In other blogs, the additional column “term_order” is not created during the activation and the plugin simply doesn’t work.

The function:

function customtaxorder_activate() {
	global $wpdb;
	$init_query = $wpdb->query("SHOW COLUMNS FROM $wpdb->terms LIKE 'term_order'");
	if ($init_query == 0) {	$wpdb->query("ALTER TABLE $wpdb->terms ADD <code>term_order</code> INT( 4 ) NULL DEFAULT '0'"); }
}

can be something like:

function _customtaxorder_activate() {
	global $wpdb;
	$init_query = $wpdb->query("SHOW COLUMNS FROM $wpdb->terms LIKE 'term_order'");
	if ($init_query == 0) {	$wpdb->query("ALTER TABLE $wpdb->terms ADD <code>term_order</code> INT( 4 ) NULL DEFAULT '0'"); }
}
function customtaxorder_activate($networkwide) {
	global $wpdb;
	if (function_exists('is_multisite') && is_multisite()) {
		if ($networkwide) {
			$curr_blog = $wpdb->blogid;
			$blogids = $wpdb->get_col("SELECT blog_id FROM $wpdb->blogs");
			foreach ($blogids as $blog_id) {
				switch_to_blog($blog_id);
				_customtaxorder_activate();
			}
			switch_to_blog($curr_blog);
		}
	} else {
		_customtaxorder_activate();
	}
}

Ciao;
Matteo
