Bug description:array_multisort uses second array to sort

Description:
------------
I thought array_multisort sorts the first array and orders the consequent
arrays 
accordingly. Changing $sort['C'] to 3 indeed makes the error message go
away so we think 
the error is only triggered if the sort does not happen in the first array.
This is 
related to http://bugs.php.net/bug.php?id=54259
but I have simplified
Brad's script as 
much as I can -- and he reported as a feature request. I think this is a
bug. At least a 
documentation bug.

Test script:
---------------
$sort['A'] = 2;
$sort['B'] = 1;
$sort['C'] = 1;
$menu['A'] = 0; 
$menu['B'] = (object) array(0);
$menu['C'] = 0;
array_multisort($sort, SORT_NUMERIC, $menu);


Expected result:
----------------
No error message shown

Actual result:
--------------
PHP Notice:  Object of class stdClass could not be converted to int in 
/tmp/chx_array_multisort.txt on line 11
