I guess here "$2" is the new version, this is what I can see on my machine:
# dpkg --compare-versions 3.1.0-3ubuntu0.0 lt 3.1.0-3ubuntu0.1~; echo $?
0
# dpkg --compare-versions 3.1.0-3ubuntu0.1 lt 3.1.0-3ubuntu0.1~; echo $?
1
# dpkg --compare-versions 3.1.0-3ubuntu0.2 lt 3.1.0-3ubuntu0.1~; echo $?
1
# dpkg --compare-versions 3.1.0-3ubuntu0.3 lt 3.1.0-3ubuntu0.1~; echo $?
1
it returns true at each update, but i don't know what you have in the 'then' part
