Thanks for your advises.
There are two problems with WixBundleInstalled:
1) I have to distinguish 3 states: version is same, current version is lower
than installed version, current version is higher than installed version. But
WixBundleInstalled only has value 0 or 1.
2) Which is even worse: I can't get this to work. I tried
var x =
_bootstrapperApplication.Engine.StringVariables["WixBundleInstalled"];
and
var y =
_bootstrapperApplication.Engine.NumericVariables["WixBundleInstalled"];
Both returned 0. When I handle the DetectRelatedBundle event however, I see
that the bundle is already installed in the current version (which is
correct)...

The wixstdba uses WixBundleInstalled variable to determine maintenance mode. I
would recommend doing the same.
