Last I knew, ties were decided by the internal document id. you can control this any way you want, just include a Sort object in your query with multiple SortFields. Two pre-defined SortFields types you can use are FIELD_SCORE and FIELD_DOC and you can add any number of other fields to sort by, see the API for Sort and SortField...
The default is pretty much equivalent to a Sort object with two SortFields, the two mentioned above...
