My proposal: build a dynamic pattern from your @array_code 

my @array_code = qw(x-01 x-02 x-03 x-04 v-05 v-06 v-07 x-08 x-09 x-10 
+x-11);
my $pattern = "(".join("|", @array_code ).")";


my @files = qw(1234567_x-01_2013_03.txt 1234667_x-03_2013_03.txt  0034
+567_y-01_2013_03.txt 1234567_v-01_2013_03.txt  233567_v-05_2013_03.tx
+t 1234567_x-55_2013_03.txt);

for my $file (@files) { 
    next if $file =~ /$pattern/;
    print $file,"\n";
}
