I am going to answer this question on the basis that you have already received an interview. As mentioned above by Crow, this is a complex question and given the bonuses and high weighting of the interview, there is no straight answer. If you have been offered an interview (and have bonuses) that is what you should focus on. It doesn't matter about scores as much now, a poor interview performance is likely to be uncompensated by high scores. At this stage consider your scores sufficient and focus on the interview.
