You can add any custom rule condition with the alg_wc_order_status_rules_do_apply_rule filter.
Example #1: Check if the customer had any previous orders
add_filter( 'alg_wc_order_status_rules_do_apply_rule', function( $do_apply, $order, $rule_id, $args ) {
/**
* First we are checking:
* a) if it's the rule we need,
* b) if the rule's status, etc. conditions are fulfilled,
* c) if it's not a guest's order.
*/

* Now we check if the current user had any previous orders.
* @see https://github.com/woocommerce/woocommerce/wiki/wc_get_orders-and-WC_Order_Query
*/

'customer_id' => $user_id, // from the same user only
'date_created' => '<' . $order->get_date_created(), // older orders only
'limit' => 1, // one order is enough
) );
/**
* Finally we set the rule to be applied only to orders from new customers.
* If we'd need to apply the rule only for old customers instead, we'd use:
* return ( ! empty( $_orders ) );
*/
return ( empty( $_orders ) );

Example #2: Check if the customer has purchased this product in any of his previous orders

Example #3: Check if the order has any products with stock quantity lower than or equal to 5
