SSRS - How to Split a Single Column to Multiple Columns

Let us assume we have dataset with below fields:
 

StudentName	Score
A	2,90,100,8
B	1,80,100,7
C	1,90,100,2

Score can be defined as (attemptno, scored, total, rank)
Now, I want to split this score column to four columns as 'Attempts', 'Scored', 'Total', and 'Rank'. To add this column we need to add below expression to text boxes.

=(Split(Fields!Score.Value,",")).GetValue(0)
=(Split(Fields!Score.Value,",")).GetValue(1)
=(Split(Fields!Score.Value,",")).GetValue(2)

=(Split(Fields!Score.Value,",")).GetValue(3)
