WORTH NOTING ON TV

SUNDAY A Christmas Carol (CBS, 9-11 p.m.): As Scrooge, George C. Scott joins the ranks of great Bah-Humbug artists in this 1985 dramatization of the Dickens novel, filmed on location in Shrewsbury, England, and well worth this rebroadcast.

MONDAY The Homecoming, A Christmas Story (CBS, 12:30-2:30 p.m.): Earl Hamner's award-winning 1971 drama about a rural family in the depression era - starring Richard Thomas and Patricia Neal - was the basis for TV's well-loved ``Waltons'' series.
