"ORDER BY" issue - is this a bug?

Greetings,

I've been using postgresql for some time and currently am using it in three
different environments (specific details below) w/ the first two being 6.5.x
releases and the third  7.0.2-2:

I've come across what I consider an odd sorting anomaly in 7.0.2-2 where running
the following query:
select headline from headlines where headline like 'Alb%' order by 1 ;

The results in the 7.0.2-2 install come back case-insensitive and oblivious to
punctuation.  This seems to me to be a bug; case-insensitive ordering can be
achieved with the use of UPPER() or LOWER() functions, otherwise why have the
functions.  Also, I've created three test databases on the 7.0.2-2 system each
with a different specified encoding  -
         List of databases
  Database  |  Owner   | Encoding
------------+----------+-----------
 headlines  | deckard  | WIN
 headlines2 | deckard  | SQL_ASCII
 headlines3 | deckard  | LATIN1

to see if the results are different.  Each of the encodings produces the same
anomalous results.

Any help in this regard as well as resolving it would be appreciated.  Details
of systems and schema are appended below.
