When using an array node with children of prototype array and `useAttributeAsKey`, using numerical values for the keys throws an exception. For example (`useAttributeAsKey('id')`):

``` php
array(
array('foo', 'bar', 'id' => 'a')
)
);

// works and is the same as above
array (
'thing' => array(
'a' => array('foo', 'bar')
)
);

// works
array(
'thing' => array(
array('foo', 'bar', 'id' => 42), array('baz', 'qux', 'id' => 1337),
),
);

// works with this patch and is the same as above
array(
'thing' => array(
42 => array('foo', 'bar'), 1337 => array('baz', 'qux'),
),
);
```
