I think, you just need to join twice with tags table, and this will
give you what you want:
my $product_rs = $schema->resultset('Product')->search_rs(
{ # conditions will be AND'ed by default
'product_tags.tag_id' => 'tagA',
'product_tags_2.tag_id' => 'tagB',
}, {
join => [ 'product_tags', 'product_tags' ],
}
);
For manuals, see here:

PS: I will not be surprised, if this variant will be faster than all other ;)
