I think this works:

   REM Sun 1 MSG Town A
   REM Sun 8 MSG Town B
   REM Sun 15 MSG Town C
   REM Sun 22 MSG Town D

   # this test ensures that the "Town E" reminder doesn't wander
   # off into the first Sunday of next month
   REM Sun 29 SATISFY 1
   IF day(trigdate()) >= 29
      REM [trigger(trigdate())] MSG Town E
   ENDIF
