Been in the box office biz for more than 35 years and not splitting triples is a fairly common practice. But with the advent of online ticketing and live seating charts the secret is out in the open. The work around is, as has been said, call the box office. We will always split the triple over the phone. Or if you don't want to deal with a person, sometimes you can get the seats you want by splitting the transaction into two online orders - but keep in mind that some ticketing systems will not allow a patron to leave a single seat.
