I used Efrain's code and got the scores for different parents sets in a giving order and a giving variable. I used sprinkler dataset. The order I used is 0, 1, 2, 3, 4, 5, 6, 7. Each number means the 1st column (or the 1st variable), the 2nd column (or the 2nd variable), the 3rd column, ..., in the dataset file.
The scores are following:
-72.300931187921023
