Barbara Scott has two sons, named Paul and James in order of age, if Taboo III is to be believed, yet James Scott, nicknamed "Jimmy," never appears in Taboo.
Barbara Scott (Kay Parker) enters Gina's (Juliet Anderson) apartment late in the film, and a Jim Croce album is then clearly visible. But when Barbara leaves Gina's apartment, moments later, a different album has appeared.
When Diane (Tawny Pearl) walks in on Paul Scott (Mike Ranger) and Sherrie MacBride (Dorothy LeMay) going "at it again," she is clearly shown to be barefoot. However, when Paul and Diane engage in the full-blown sex scene, at Sherrie's urging, Diane is just as clearly shown, now, to be wearing open-toed spike-heeled sandals.
When Turk Lyon, as Christopher Scott, announces after a rather limply performed sex scene that he has had enough of his marriage to Barbara Scott (Kay Parker) and is leaving her, the clothes he is pulling on as he says this to her clearly do not fit him; e.g., his shirt's sleeves are too short.
Kay Parker initially refers to Milton Ingley as "Jerry Morgan", then later calls him "Jerry Marvin" when talking to her son. Further on in the film, the realty office that Morrison works at is called "Morgan Realty". Therefore it appears the correct name is "Jerry Morgan".
