Phone Number Input Fix Golf

 The problem:
Let's say you have an HTML form out on the Web for information gathering
for a business that will contact the customers requesting information by the
phone number they enter in a single text input box. The box does not restrict
character input in any way. We will assume for argument sake that the person
filling out the form will enter the phone number keeping all the area code digits
together, all the prefix digits together and all the extension digits together. We
will also assume it is a standard US 10-digit phone number. The person filling out
the form can use any number of characters or spaces between the groupings.
 The challenge:
In the fewest number of characters of perl code, print any phone number entered
to STDOUT always in the format ($_ can equal phone number from form):
sprintf("(%.3s) %.3s-%.4s", $area, $prefix, $extension);
If all three parts are not present, the script must die (no message necessary for challenge).
To score, count all keystrokes in your code. 1 point for each keystroke. Fewest
points wins!
My best score is 41.
[spoiler]/(\d{3}).*(\d{3}).*(\d{4})/?print"($1) $2-$3":die;[/spoiler]
Good Luck.
P.S. Jasmine - The spoiler mnemonic is not working correctly. The text showed up until I turned it white.
