How to use filters that contain other filters?

Okay this must be a really noob question…

Say the relevant filter in the php is defined like:

$content        = sprintf('<%1$s class="entry-title %2$s">%3$s</%1$s>',
                apply_filters( 'tc_content_title_tag' , 'h1' ),
                apply_filters( 'tc_content_title_icon', 'format-icon' ),
                get_the_title( $page_for_post_id )
           );
$content        = apply_filters( 'tc_page_for_post_header_content', $content );

So I’m trying to use the filter ‘tc_page_for_post_header_content’ to add itemprop="itemReviewed" inside the <h1> tag.

So this is what I tried in my child theme’s functions.php:

add filter( 'tc_page_for_post_header_content' , 'add_structured_title');
function add_structured_title() {
    if (is_singular('post') ) {
        return sprintf('<%1$s itemprop="itemReviewed" class="entry-title %2$s">%3$s</%1$s>',
                apply_filters( 'tc_content_title_tag' , 'h1' ),
                apply_filters( 'tc_content_title_icon', 'format-icon' ),
                get_the_title( $page_for_post_id )
           );
    }
    else {
        return sprintf('<%1$s class="entry-title %2$s">%3$s</%1$s>',
                apply_filters( 'tc_content_title_tag' , 'h1' ),
                apply_filters( 'tc_content_title_icon', 'format-icon' ),
                get_the_title( $page_for_post_id )
           );
    }
}

As you can imagine that failed terribly.

I think I probably have to add $page_for_post_id as an argument in the function? Also, how do I deal with the filter calling other filters that is outside my child theme’s functions.php?

Thanks for your help! ??
