A pass is a pass. The score will not be reflected in the certification, and thus, no one knows what score you got unless you show them the score report.
In fact, if you are thinking of taking it again for scoring improving, why dont you have a better preparation for the 1st time?
It is not worth to pay for another USD$125 to get, say, a 10% score improvement, rather, it is better for you to invest your time and money in other certifications.
