man trap:
"       The  condition  can  be EXIT, 0 (equivalent to EXIT), or a
signal specified using a symbolic name, ***without the SIG prefix***, as
listed in the tables of
       signal names in the <signal.h> header defined in the Base
Definitions volume of IEEE Std 1003.1-2001, Chapter 13, Headers;  for 
example,  HUP,  INT,
       QUIT,  TERM.  Implementations  may  permit  names  with  the SIG
prefix or ignore case in signal names as an extension. Setting a trap
for SIGKILL or
       SIGSTOP produces undefined results.
" (emphasis mine)

Accepting SIG* is not guaranteed, if it works it's an extension

Here's an example from the same man page
"trap - INT QUIT TERM EXIT"
