What version of TPU?  I haven't examined this in detail but your patterns look ok.  Why not try:

 ( (span("0123456789") + "."                      + notany("dD")) ! aa.X
 | (span("0123456789") + "." + span("0123456789") + notany("dD")) ! aa.bbX
 | (                     "." + span("0123456789") + notany("dD")))!   .bbX

and report the results.

You can use partial pattern assignment on your patterns to see who is matching what.
