Dangit Chris, beat me to it :)
Switch on verbose logging (http://support.microsoft.com/kb/314852),
and look for something like this:
MSI (c) (14:28) [11:56:32:469]: Doing action: FindRelatedProducts
Action 11:56:32: FindRelatedProducts. Searching for related applications
Action start 11:56:32: FindRelatedProducts.
FindRelatedProducts: Found application: {XXXXXX-XXXX-XXXX-XXXX-XXXXXXXXX}
Immediately following this you should get some PROPERTY CHANGE events,
which will be the property defined in the upgrade table as what should
be set when it finds an upgrade.
