lscpu only uses MHz (as well as the kernel in /sys), but you are
correct that "CPU(s) frequency scaling" sounds better.

I am doubtful that we can alter column names. The usual recommendation
is to use "-o <colname>" to obtain output for the script. Changing a
column name would cause a backwardly incompatible modification. It may
be feasible to introduce a column alias, but I am uncertain if it
would be worthwhile.
