Spill and Spell
Spill and Spell from Phillips was originally published in 1958 or 1959. Scoring is determined by squaring the number of letters in the words spelled (e.g. making a 3 letter word and a 4 letter word would net 25 (9+16)) and subtracting the square of unused letters.
The 2003 Endless Games edition of Spill and Spell includes 22 letter cubes and is scored differently, assigning a point value to each letter based upon the length of the word it is part of, with crossed words scoring the shared letter twice, possibly with two different values.
