Yes, it might not a bug, rather a minor inconsistancy.
I must say I expected it to get reindexed as well.

From sources:
/* If all arrays are empty or have only one entry,
we don't need to do anything. */
According to that, this is the expected behaviour.
This was for empty arrays first, but Andrei changed it
later with this commit:
array.c:r1.43 (PHP array_multisort) Fix the array_size test.
Assigning to Andrei who should decide whether the reindexing should be
done for 1 element arrays or not.

Description:
------------
array_multisort() will reindex the array but not if array length is 1
Produced and reproduced in php.4.3.x and up to 5.beta
Similar (but not the same) as
http://bugs.php.net/bug.php?id=12572
(different function, 12572 is sort() )
Reproduce code:
---------------
<?php
// array_multisort() will reindex the array but not if array length is
1, is
this a bug?
// array length 1
$a = array(1=>1);
array_multisort($a);
var_dump($a);
// output: array(1) { [1]=> int(1) }
// first index 1, not reindexed!
//----------------------
// array length 2
$a = array(1=>1,2);
array_multisort($a);
var_dump($a);
// output: array(2) { [0]=> int(1) [1]=> int(2) }
// first index 0, reindexed!
?>
Expected result:
----------------
Array should be reindexed to:
output: array(1) { [0]=> int(1) }
on first attempt (where array length = 1)
Actual result:
--------------
output: array(1) { [1]=> int(1) }
array is not reindexed
