Lennaert, thanks for the quick response but I am still confused as to how to use your advice.
First I set the tempScore:
Set tempScore to tokenat(tempRow,1,"""&SCORECOLUMNAME&"":")
Then to set the array value:
Set value at (highScoreCount,1) to tokenat(tempScore,0,"""")
Not sure where I'd use the score=replace(score,",","")
