Right.

If the version number begins with a 3 and is three digits (before the
decimal) then it is treated as the old-style version number.

I could change the way parsing for the packages works, but that would
mean your package would only work for 5.1.2 and later versions (which,
technically, means you'd want to change the required-core-version :).
