You want a die 'timeout'; in your $SIG{ALRM} that will break you out at the end of your eval (put a ; at the end of that eval) then put your code catch code... like so

$SIG{ALRM} = sub {die 'timeout'};
while ( $number < 10 ) {

   eval {

      alarm(3);

      print $number;
   
      if ( $number == 3 ) { sleep 4; } # This is to simulate the delay
+ the routines may generate...
   
      $number++;
   
      print "\n";
   };

   alarm(0);

   if($@ eq 'timeout') {
     next;
   } else {
     die $@;
   } 

}

Not tested, but should get you pointed in the right direction. Alarm 0 is important to unset the alarm.
