Can anyone explain why this does not put the record with "PBMTU" (Pediatric Bone Marrow Transplant Unit) in the last position?

It's for an internal report and really doesn't matter, except that I'm really surprised it comes out in this order.

CREATE CURSOR Dummy (Rec N(1), MyField C(60))
INSERT INTO Dummy (Rec, MyField) VALUES ;
    (1, "CLINICAL ASSOCIATE - Nurse Practitioner")
INSERT INTO Dummy (Rec, MyField) VALUES ;
    (2, "CLINICAL ASSOCIATE - Nurse Practitioner")
INSERT INTO Dummy (Rec, MyField) VALUES ;
    (3, "CLINICAL ASSOCIATE - Nurse Practitioner")
INSERT INTO Dummy (Rec, MyField) VALUES ;
    (4, "CLINICAL ASSOCIATE - Nurse Practitioner")
INSERT INTO Dummy (Rec, MyField) VALUES ;
    (5, "CLINICAL ASSOCIATE - Nurse Practitioner")
INSERT INTO Dummy (Rec, MyField) VALUES ;
    (6, "CLINICAL ASSOCIATE - Nurse Practitioner")

SELECT Rec, ;
    PADR(ALLT(MyField) + IIF(Rec = 3, " - PBMTU", ""), 50) ;
    AS MyField ;
    FROM Dummy ;
    ORDER BY 1, 2
