Sqlite3顺序上的整数不起作用（即使是索引）

HY，

谁能解释一下这个？

sqlite> .schema LastFM
CREATE TABLE LastFM(id INTEGER PRIMARY KEY, AlbumTitle TEXT, Hoerer INTEGER);
CREATE INDEX Hoerer_Index ON LastFM( Hoerer DESC );
sqlite> Explain SELECT * FROM LastFM ORDER BY Hoerer;

我有一个表LastFm（id INTEGER PRIMARY KEY，AlbumTitle TEXT，Hoerer INTEGER）并用csv文件在python中填充数据：

reader = csv.reader(open(csvFileName, 'r'), delimiter=';')
    for row in reader:
        to_db = []
        for col in row:
            to_db.append(unicode(col, "utf8"))
        cur.execute("INSERT INTO LastFM(AlbumTitle, Hoerer) VALUES (?, ?);", to_db)
    sqlConnection.commit()

但是“order by”功能无法正常工作 . 我已经尝试在我想订购的列上创建一个索引，但它也不起作用 .

一些提示？
