Well, there's quite a mess with Fingering_engraver and New_fingering_engraver...
If you _need_ to use the context-properties
then you need to use event-chords. Furthermore StringNumber and
Strokefinger applied outside of a chord don't follow tweaks/overrides
of 'direction.
Fingering does!

Though they all follow the direction-modifiers ^/_

    b-2 -\5 -\rightHandFinger #1
    b^2 ^\5 ^\rightHandFinger #1
    b_2 _\5 _\rightHandFinger #1

    b-\tweak direction #UP -2
     -\tweak direction #UP -\5
     -\tweak direction #UP \rightHandFinger #1

    b-\tweak direction #DOWN -2
     -\tweak direction #DOWN -\5
     -\tweak direction #DOWN \rightHandFinger #1

    \once \override Fingering.direction = #UP
    \once \override StringNumber.direction = #UP
    \once \override StrokeFinger.direction = #UP
    b-2 -\5 -\rightHandFinger #1

    \once \override Fingering.direction = #DOWN
    \once \override StringNumber.direction = #DOWN
    \once \override StrokeFinger.direction = #DOWN
    b-2 -\5 -\rightHandFinger #1

Alas, if you need directions like left or right or a list of
directions like '(up left down), then you can't avoid the event-chord,

Not sure what you mean...
