Using term queries with two different script based custom filter score query

I need to to club a set of term queries with two different script based custom filter score query.
I have done this clubbing of queries and filters by using the bool filter but when i run this, i get results with score =1.

I am not sure whether this approach is correct or not.
Also i am not able to get why the score is 1.

Please help.

Thanks in advance.
