I would do it in the following way:
Add the remove commands for the previous versions as install/upgrade
commands to the 10.1.2 package.
<install cmd="msiexec /x ...">
<condition>
<check type="uninstall" condition="versionequalto" path="..."
value="10.0.0" />
</condition>
</install>
This will execute the command only if the registry contains the
uninstall information of the specified version.
This requires using WPKG 1.3.0
