Description:
------------
I'm trying to use different types of cursor orientations. Even example from official manual does not work.

Reproduce code:
---------------
$dsn = 'mysql:dbname=...';
$dbh = new PDO($dsn, $user, $password);

$sql = "SELECT * FROM genres WHERE 1 ORDER BY id";

$stmt = $dbh->prepare($sql, array(PDO::ATTR_CURSOR => PDO::CURSOR_SCROLL));
$stmt->execute();
$row = $stmt->fetch(PDO::FETCH_NUM, PDO::FETCH_ORI_LAST);
do {
  $data = $row[0] . "\t" . $row[1] . "\t" . $row[2] . "\n";
  print $data;
} while ($row = $stmt->fetch(PDO::FETCH_NUM, PDO::FETCH_ORI_PRIOR));

$stmt = null;


Expected result:
----------------
3	Fighting	
2	Arcade/Puzzle	
1	Action/Adventure	

Actual result:
--------------
1	Action/Adventure	
2	Arcade/Puzzle	
3	Fighting
