Ah, that's the reason for these strange suffixes. Thanks for the
explanation! :-)

I don't think so. Because the first added character is still a dot.
Adding +0 +1 +2 etc. instead of .0 .1 .2 etc. may work better, but is
probably not completely sane either.

I generally would not try to squeeze suffix preference into the
version comparison itself, but do the suffix ordering in a separate
dimension, e.g. first sort by version and if there's more than one
file for the newest version, then sort them by suffix priority.
