I don't think people would call it "process title". Whatever, this is a faq; check in particular perldoc -q "perl's command line". To quote from it: 
To actually alter the visible command line, you can assign to the vari
+-
able $0 as documented in perlvar.  This won't work on all operating
systems, though.

Appears to work: 
$ perl -e '$0="foo"; 1 while 1' &
[1] 19748
$ ps U blazar
  PID TTY      STAT   TIME COMMAND
19585 ?        S      0:00 sshd: blazar@pts/0
19592 pts/0    Ss     0:00 -bash
19748 pts/0    R      0:06 foo
19758 pts/0    R+     0:00 ps U blazar

Update: thanks to tirwhan for suggesting s/(?<=ps )aux | grep(?= blazar)/U/.
