I just grepped through the code and found out that number-or-markup?
is already defined. SO you can use it like this:

#(define-markup-command (sus layout props num-or-markup)
  (number-or-markup?)
  (interpret-markup layout props
    (if (number? num-or-markup)
        -- stuff for numbers --
        -- stuff for markup --
   )))

HTH,
