json (LitJSON) from PHP array.. How?

I can't figure out how to get an array w$$anonymous$$ch has been received via WWW, from a PHP server. More specifically, I don't know what the type should be.

The data I receive from php, is sent via a standard json_encode() and received fine in Unity:

[[],{"score":"2821"},{"score":"575"}]

The problem occurs when trying to get json to "unpack" it:

I've tried:

string[] str = JsonMapper.ToObject<string[]>(www.text);

W$$anonymous$$ch gives t$$anonymous$$s error in Unity: JsonException: Type System.String can't act as an array.

Same for anyt$$anonymous$$ng else I throw at it, even an ArrayList..

It's somet$$anonymous$$ng quite obvious, I know it, can someone help?
