I don't think, that it would work with
DATA 'anyscript'
because this is reading the source, not executing it.

But a WMS is doing what you are asking for:
 > create Raster images on the fly
so perhaps you could use your script as WMS and call it with
CONNECTIONTYPE WMS
CONNECTION "http://.../yourscript"

you could add the parameters your script needs directly to the 
connection-string.
CONNECTION "http://.../yourscript?param1=gtf&gt2=..."

Regards, Jörg
