Of course dots matter. Especially when supporting multi-dotted version numbers.
And in your example 864 is clearly a higher number than 8 (or let's say 864.00
is clearly higher than 8.64).

WPKG version compare takes dots into accounts. In old WPKG versions only integer
values (no dots) were allowed. Now WPKG compares the version numbers starting
from the left side.

So for me this is not a bug but an expected behavior. Anyway there are some
reports in Bugzilla asking for an extension - but none of them requests to
ignore dots. This would lead to quite strange behavior anyway.
However it's planned to rework the version parsing algorithm slightly in the
future but I do not have an algorithm in mind which will accept 8.64 to be newer
than 864.

What you can do is to specify some <downgrade /> commands which will then do the
installation. In many cases the downgrade command would anyway look identical to
the upgrade command (either just install the package or uninstall and then
install). So in most cases it does not matter if WPKG detects if the package is
newer or older - it just detects a version mismatch and executes appropriate
commands. After that WPKG will write your (fixed) version 8.64 to the local
wpkg.xml.
