Table schema:
CREATE TABLE table_name_66 (total_orphans__total_ INTEGER, total_orphans__aids_related_ VARCHAR, maternal__total_ VARCHAR)

Question: What is the Total Orphans number when the number of Total Orphans (AIDS Related) is < 100, and the Maternal (Total) is smaller than 31,000?
SQL: SELECT MIN(total_orphans__total_) FROM table_name_66 WHERE total_orphans__aids_related_ = "< 100" AND maternal__total_ < 31 OFFSET 000
