Maybe you seeking something like this: 

#!/usr/bin/perl -w
use strict;
use 5.010;
my $str=<<TEXT;
{TAG}
0012310002 and 0012310003
{COUNT}
000000
{COUNT2}
000000 and 100001
TEXT
my %strh = $str=~ /({.+?}|^{}+)/sg;
my @and_contain = grep $strh{$_} =~ /and/,keys %strh; 
say join(' and ',@and_contain),' is 1';
Output:

{COUNT2} and {TAG} is 1
