Indeed. I did not envision such a use case, but it is quite legitimate and
interesting! I would hope that the behavior would be a linear combination
of the raw performance of each script, but whether it is indeed the case
is not that sure.

Speaking for myself, I would be fine with such a change, provided:
- that it does work:-) I'm not sure what happens by the script selection process, it should be checked carefully
becauseit was not designed with allowing a zero weight, and it may depend on its/their positions. It may already
work,but it really needs checking.
- I would suggest that a warning is shown when a weight is zero, something like "warning, script #%d weight is zero,
willbe ignored".
- the documentation should be updated:-)
