My take on this is that the man page was originally written for
BSD, which lies on the csh side of the "great divide" rather
than the sh/bash side.
SCRIPT(1) User Commands SCRIPT(1)
[ … ]
HISTORY
The script command appeared in 3.0BSD.
I have no idea why "the history mechanism" is even mentioned
in the man page for script.

According to this man page for csh (but includes tcsh):
https://linux.die.net/man/1/csh
the "a" that modifies modifiers is a "[feature] of tcsh not found
in most csh(1) implementations (specifically, the 4.4BSD csh)". It
appears that bash supports it syntactically, but not its semantics.
I'm not sure why you mentioned this shell detail specifically.
