There is a way to  test for an empty string:
  GotoIf($[${CALLERIDNUM} = ]?3:2)

My guess is that this won't work. Instead look into DBput and DBget and
do something like 

  DBput(last-call/${CALLERIDNUM}=value)

The advantage of this is, by the way, that the last caller data will also 
be available after a restart of Asterisk.

You'll jump to priority 4, not extension 4.

Look at Macros.
