Tuple types not validated properly when using additionalProperties restriction

What steps will reproduce the problem?
1. Create schema:
{
    "type": "array",
    "items": [{"type": "string"}, {"type": "integer"}],
    "additionalItems": {"type": "object"}
}
and an instance:
["abc", 123, "def"]

2. Attempt to validate the instance using the schema.

What is the expected output? What do you see instead?

Expected: An object indicating the instance is invalid according to the schema.
Instead: The returned object indicates the instance is valid.

What version of the product are you using? On what operating system?

jsonschema-b4.js, Firefox 3.5.1, Windows Vista

Please provide any additional information below.

My solution is on lines 142-152 of the attached file jsonschema-b4.2.js.
Note that additionalProperties is changed to additionalItems in this
solution.  Simply changing it back to additionalProperties would bring the
implementation back into conformance with the proposal.

jsonschema-b4.2.js (The implementation modified with the solution to this
issue, another issue I posted, a modification of the additionalProperties
to additionalItems restriction, as well as some other modifications for
personal preference which don't affect conformance to the JSON Schema proposal)
