2 good resources about versioning can be found here:

Debian versioning:

https://www.debian.org/doc/debian-policy/ch-controlfields.html#version

A blog entry from Robie basak, explaining Ubuntu versioning in details:

https://linkprotect.cudasvc.com/url?a=http%3a%2f%2fwww.justgohome.co.uk%2fblog%2f2015%2f01%2fubuntu-package-versions.html&c=E,1,zprTYA8GmUjXzAXeLr65RNOcLymTKv8YKDT_nujlxA3SOe_DX6kUSElH0CrHkbCHuc0GyhQSJi208QDtWUb0LbJ6sY26kt1ZXT010LxcYg,,&typo=1

A good way of making sure a version is greater than other is to execute:

dpkg --compare-versions 1ubuntu1.0-1 gt 1ubuntu1.0~1 && echo greater
than || echo less than

and check.
