Try the following...
Code:
#!/usr/bin/perl

while(<DATA>){
    chomp;
    my $count=0;
    @fields=split(/\s+/,$_);
    $count++ if $fields[3]=~/^($fields[1]|$fields[2])$/;
    $count++ if $fields[4]=~/^($fields[1]|$fields[2])$/;
    print "$_\t$count\n";
}
__DATA__
Item A B C D
1 201 3101 3101 201
2 3101 201 202 3101
3 3101 201 201 3102
4 3101 201 3202 202

Or as a (slightly less clear) one liner...

Code:
$ perl -ne 'chomp; $c=0;@f=split;map{$c++ if/^$f[1]|$f[2]$/}@f[3,4];print "$_ $c\n";' tmp/tmp.dat
1 201 3101 3101 201 2
2 3101 201 202 3101 1
3 3101 201 201 3102 1
4 3101 201 3202 202 0
