Short version:  Gogogo!

Slightly longer: Make sure to strictly define the semantics of 
non-integer parts.

It might seem obvious at first - "peru" being "slight fork of 
micro-version 5". But perhaps sometimes a local branch wants to release 
a sneak preview, e.g. "almost micro-version 6".  Should that then be 
labeled 23.2.6-peru or (since 5-peru is taken already) 23.2.6.peru2?

In Debian we allow both letters and digits in all parts, and use special 
sign "~" to indicate "almost" and "+" to indicate "just above". And we 
treat 0 (zero) equal to a missing trailing part. And more nitpicking...

I do not, however, recommend you to adopt such complex scheme.  I 
suggest instead (as might actually be what imply by the above summary) 
that the 3 first parts are strictly digits and intended only for 
mainline releases, while an optional 4th part is strictly for 
non-mainline use and allows [a-z0-9] (but nothing else - no dash, 
underscore, capital or non-ASCII letters, +~ or whatever). Then use 
simple C locale sort order, and leave it to local branches if they want 
to use only letters or also leading and/or trailing digits.
