[Part 4] Create convenience constructors for the Score and TrainAndScore transforms.

[zeahmed]

This work item is related to #371 and is the 3rd work item in series of creating convenience constructor (cf. #380, #487 and #518). In this work item, convenience constructors will be created following set of transforms. There is also a possibility that the creation of convenience constructors for these transforms is not possible due to complex nature of these transform.
