InstallShield tech support acknowledged the problem and found a 'new'
workaround:

----
Please note that the following appears to provide a workaround to the patch
creation error with MinorUpdateTargetRTM when using patchwiz.dll version
3.1:
1. Set the MinorUpdateTargetRTM setting on your patch configuration to Yes.
2. Go to the Direct Editor view and locate the MsiPatchMetaData table.
3. Enter a value into the Company column for the row that contains the
MinorUpdateTargetRTM property.
4. Save the project.
5. Build the patch configuration from the Patch Design view, and ensure that
patchwiz.dll version 3.1 is used to build the patch.

You can verify that the built patch contains the MinorUpdateTargetRTM
property by opening the patch directory with Orca 3.1.
