The only Mathworks-provided score() function is an operation specific to creditscorecard objects created by the Finance Toolbox.
The table that KSSV mentions is only for the second input; the first input needs to be a creditscorecard object.
We cannot send you the code for the method; if you do not have the finance toolbox then it is useless to you, and it would violate our license agreements to send it.
Might I suggest that possibly you are looking for zscore() instead of score()? zscore is part of the Statistics and Machine Learning toolbox.

I am not familiar with Huber's score function. Is it related to the 'huber' option of https://www.mathworks.com/help/stats/robustfit.html ?
