I would just add a process interrupt handler to your script. Then just zap the program and it will call a sub to do stuff like write your logfile before exiting. 

$SIG{INT} = \&zap;   # trap interrupts and run &zap sub

sub zap {
   print "You zapped me!\n";
   # do some stuff
   die;
}

sleep 1 while 1;

This code will obviously not finish until you zap it, like sleeping beauty it will keep on sleeping. When you zap it the $SIG{INT} handler calls the zap sub rather than just exiting allowing you to do whatever.

Hope this helps.
