You have to use the SQL-standard syntax for ORDER BY, ie column name or
number, no shortcuts:

    SELECT ..., UPPER(last_name) AS upper_last_name
    UNION
    SELECT ..., UPPER(last_name) AS upper_last_name
    ORDER BY upper_last_name;

or if you prefer, ORDER BY n where n is the ordinal number of the
column.
