Ask your operating system provider.
On my RHEL 3 Linux system it works as you want it to:
CREATE TABLE mexico(id integer PRIMARY KEY, val text NOT NULL COLLATE "es_ES.utf8");
INSERT INTO mexico VALUES (1, 'cota'), (2, 'álvarez'), (3, 'chavez');
SELECT * FROM mexico ORDER BY val;
id | val
----+---------
2 | álvarez
3 | chavez
1 | cota
(3 rows)
