Ad hoc I have no solution by using a single regexp but a quick&dirty  
solution would be this snippet:

"""
$TM_FILENAME ${1:args}
"""

     if len(argv) != ${2:ruby -e 'p "$1".strip.split(/\S+/).size'}:
         exit(1)
     $0


invoke it, type something for args, press TAB, press CTRL+OPT+R (it  
executes the selection in bash and replaces the selection by the result)

Or write a tmcommand which counts the words in selection and replaces  
the selection with that number.
then:
"""
$TM_FILENAME ${1:args}
"""

     if len(argv) != ${2:$1}:
         exit(1)
     $0

type args, press TAB, invoke that tmcommand
