You might need two queries - one to order the records and another to give you your MAX.

SELECT CustId, OrderNumber, total_price FROM yourtable INTO CURSOR curs1 ORDER BY CustId, total_price

SELECT CustId, LAST(OrderNumber), LAST(total_price) FROM curs1 INTO CURSOR endresult GROUP BY CustId

In the second query, LAST(total_price) and MAX(total_price) should give you the same thing.
