[BUG] ScoreSort returns SortOptions.Kind.Doc

[lflores-apex]

What is the bug?

When creating a ScoreSort it ends up behaving as _doc sort because the kind of ScoreSort is SortOptions.Kind.Doc

How can one reproduce the bug?

SortOptionsBuilders.score().build()._sortOptionsKind() // == _doc

What is the expected behavior?

SortOptionsBuilders.score().build()._sortOptionsKind() // == _score

What is your host/environment?

Windows 10

Do you have any screenshots?

Do you have any additional context?
