This has nothing to do with JSON at all, same happens with this:
<?php
$a->{"1"} = "one";
$foo = (array) $a;
var_dump($foo);
var_dump($foo["1"]);
?>

Description:
------------
json_encoding and json_decoding an array with string indices as numbers
starting from anything else than zero will create an array that can't be
used to fetch elements from.
Note that this only happens when you cast the resulting object from
json_decode to an array.
Please look at the attached code example for more information about
this bug.
Reproduce code:
---------------
<?php
$array = array("1" => "one"); // array("0" => "zero")
works fine.
$foo = (array) json_decode(json_encode($array));
// $foo = json_decode(json_encode($array), true) works fine
var_dump($foo);
// array(1) {
// ["1"]=>
// string(3) "one"
// }
var_dump($foo["1"]); // Outputs PHP Notice and NULL expected "one"
?>
Expected result:
----------------
I expect the last var_dump to output "one"
Actual result:
--------------
The last var_dump outputs NULL and a PHP Notice "undefined index: 1" is
shown
