Your best option would be to just not use []'s as part of the section name.
/writeini -n filename something n1 some text
This would, of course, mean that you'd have to change your current INI file(s) to remove those extra []'s, but it saves you the problem and then it would work regardless of version.
Note that you can also check $version and have your script do something different based on what version is being used.
