No need to use a regex if your split works fine. besides that it is hard to create a regex without knowing what your data looks like. For the summing: simply create a variable and use "+" 
use strict;                                              
use warnings;                                            
                                                         
my $file = 'scott.d3';                                    
my $FhIn;                 
my $all_yr_tot = 0;                               
                                                         
open $FhIn, '<', $file or die "Could not open $file: $!";
                                                         
while( my $line = <$FhIn> ) {                            
    my ($county, $year, $yr_tot) = split ' ', $line;      
      if ( $county eq 26005 )  {                          
   print "$county  : $yr_tot\n";
   $all_yr_tot += $yr_tot;                          
}                                                        
}                                                        
close $FhIn or die $!;
