RANK in nested foreach, is it working?

Hi, can't make it work:

flatRank = FOREACH groupedRecs {
    ranked = RANK recs by score DESC;
    filtered = FILTER ranked by $0 <100;
    GENERATE FLATTEN(ranked) as ($0 as rank_val, item_id, r_item_id, score);
}

Error:
Syntax error, unexpected symbol at or near 'RANK'

Yes, I've already found it. Implemented using cusotm code.
Thanks.
