Local patches can also be tricky because ConTeXt tries to freeze the definitions of many user level commands which means they can't be redefined when you use a strict overload mode (look at the lowlevel security manual for this feature).
An overload like mine is probably exactly what the strict overload mode is supposed to protect against.
The most reliable way to center you combination blocks is to put them either in a float or put a framedtext environment around it.
The project comprises several hundred source files. That's why I stayed away from rewriting the sources in the first place. I'll try to bulk-change the sources. Thanks for your explanations. Marco
