I actually just recently noticed that with scale tweens too! I'm posting this here because I believe this to be sort of the same issue. But it only happens if the scale tweens (close to) 0. If I scale to 0.1 instead there is no issue.
Here's the project adapted to show the scale problem. Notice that the sprite actually even flips width into the negative value which would be negative scale!
My guess: The tween plugin simply doesn't properly handle going into negative values and/or clamped values. These values will happen quite some with tweens like back, elastic or custom ones that intentionally overshoot the target values.
Here's the repro tweenscalebug.c3p.zip
