ORDER BY problem

Hi,

when i do the following query i get an wrong result order on my postgres
system (PostgreSQL 7.2.4 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2.2)

tb_test=# SELECT name, upper(name) FROM tb_wurst ORDER BY upper(name);
               name               |              upper
----------------------------------+----------------------------------

 American Sightseeing Chicago     | AMERICAN SIGHTSEEING CHICAGO
 AMERICANTOURS INTERNATIONAL INC. | AMERICANTOURS INTERNATIONAL INC.
 America West Airlines, Inc.      | AMERICA WEST AIRLINES, INC.
(8 rows)

The last line should IMHO be the first; but line 7 is in the correct place
compared to lines 2-6.
Has anybody any hint for me to resolve the problem?

Any help is greatly appreciated.
