It does not seem correct. If 'ta, a' and 'ta, b' is minor to 'tab, a'.
you should not get that order.

This is my result and what i think is what you expect.

CREATE TABLE sorting (name varchar);

labb=# \d sorting
Table "public.sorting"
Column | Type | Modifiers
--------+-------------------+-----------
name | character varying |

labb=# INSERT INTO sorting VALUES('ta, a');
labb=# INSERT INTO sorting VALUES('ta, z');
labb=# INSERT INTO sorting VALUES('tab, a');

labb=# SELECT name FROM sorting ORDER BY name ASC;
name
--------
ta, a
ta, z
tab, a
(3 rows)

labb=# SELECT name FROM sorting ORDER BY name DESC;
name
--------
tab, a
ta, z
ta, a
(3 rows)

What locale do you have on that database?
