Well. Here is an official source that claims that control change 120 is in
MIDI 1.0 (1995 revision). It is not the whole MIDI 1.0 spec, only a summary.
Here i one from 1990:
MIDI 1.0
Detail Specification February 1990

96 60H Data increment
97 61H Data decrement
98 62H Non-Registered Parameter Number LSB

Channel Mode Messages (See also Control Change, above)

1011nnnn 0ccccccc Channel Mode Messages.
0vvvvvvv This the same code as the Control
Change (above), but implements Mode
control and special message by using
reserved controller numbers 120-127.
The commands are:
All Sound Off.
When All Sound Off is received
all oscillators will turn off, and
their volume envelopes are set to
zero as soon as possible.
c = 120, v = 0: All Sound Off
[...]
The book "MIDI programmer's handbook", (C) 1989 by DeFuria &
Scacciaferro,
does not mention this controller. I guess that ancient MIDI instruments
manufactured before the 1995 revision can't be blamed if they aren't fully
compliant.
