I would like to set up a scripting solution based on MapScript that

Does anybody know a formula how to transform the XYZ request values
to bounding box coordinates in the Google Spherical Mercator
projection?
Just for the curious: the Bing map uses Quadkeys into the URL
instead of x+y+z, here you can find the math beyond that:

You might also want to look at mod_geocache as if supports all common
tiling schemes off of a single tilecache. It also has a demo mode that
will generate a sample OpenLayers page(s) to demo setup and access to
the cache using each tiling scheme.
