Description: incorrect result from 'order by'

Details:

The following:

drop table tst;
create table tst (
name varchar(25));
insert into tst values ('LEE,ADAM');
insert into tst values ('LEEBERMAN,JOHN');
insert into tst values ('LEE,RALPH');
select name from tst order by name;

Produces the following output:

DROP TABLE
CREATE TABLE
INSERT 3307587 1
INSERT 3307588 1
INSERT 3307589 1
name
----------------
LEE,ADAM
LEEBERMAN,JOHN
LEE,RALPH
(3 rows)

Expected output:
name
----------------
LEE,ADAM
LEE,RALPH
LEEBERMAN,JOHN
(3 rows)

I have tried databases with SQL_ASCII, LATIN1 and LATIN2
encoding with the same result.

From this small example and others involving an employee

table (80K+ records) it appears that the comma is being
parsed out prior to the sort (i.e. 'LEEB' sorts after
'LEEA' and before 'LEER').
