Because you have SELECT * .. the column names in the hash are probably lower case. You can add a print join " ", keys %$row line to check this. To fix it I would define the column names in the SELECT and use fetchrow_array like this 
#!perl
use warnings;
use strict;
use DBI;

my @col = qw(RECORD      SUBSCRIPT ID_SUBSTN CO_SUBSTN 
             AREA_SUBSTN ID_DEVTYP ID_DEVICE NAME_DEVICE 
             AREA_DEVICE ID_MEAS   ID_POINT  SITE_POINT AREA_POINT);
my $cols = join ",",@col;

# Create connection string to database point.csv 
my $dbh = DBI->connect ("dbi:CSV:", undef, undef, {
      f_ext      => ".csv/r",
      f_encoding => "utf-8",
      });

my $sth = $dbh->prepare ("SELECT $cols FROM point 
                          WHERE ID_DEVTYP LIKE 'INTELI%' 
                            AND ID_POINT  LIKE 'AUTO%'");
$sth->execute;

# Create AFS CSV with Columns
open DAT_OUTPUT,'>','AFS.csv' or die "Could not open AFS.csv : $!";
print DAT_OUTPUT $cols."\n";

# Cycle through SQL results on ROW basis and print to AFS CSV file
while (my @row = $sth->fetchrow_array) {
  print DAT_OUTPUT (join ",",@row)."\n";   
}
# Close file    
close DAT_OUTPUT;
