My point was that I have never seen slash notation used in the figured bass used in music analysis; therefore the interval figures used with these octave signs in Bravura seems to me to be more in the music analysis style and, for the same reason, the accidental should precede the number because this is also in the music analysis style that I am familiar with.
For today's score users, music analysis may indeed be a more relevant source of reference than figured bass.
But what about all the music analysis styles you're not familiar with? Would they not count?

But I had a hope that the phrase "flat-five", which probably originated in jazz and pop music and then migrated to the "serious" side, might have become international, as other pop culture phrases have become, or at least had a close parallel in other languages that might have reversed the normal word order. That is why I said that "it would be interesting to know about other languages" because I was looking to legitimize my argument from other languages. Obviously, if the phrase is limited to English, the point has no validity. And in thinking back, the point is not a strong one in any case. The stronger point has to do with the style of figuring being used as I explain above.
No offense taken, John. I meant it more along the lines of "Someone could be appalled at such an argument..." - Where is the "tongue-in-cheek" emoji when you need it?

After all, you did express an interest in knowing about other languages. And even in
my native tongue, the word order in question is the same as in English!
I believe the English expression "flat five" is quite well known among musicians worldwide. Yet I think it is very unlikely that the word order for describing intervals would ever get reversed in those languages where the "number" comes before the "accidental". Not only because old habits die hard, but also because that order makes a lot of sense. As I've said before, it makes sense that the more significant "digit" comes before the less significant "digit" (the accidental). Isn't that how our Arabic numeral system works as well? The hundreds come before the tens, the tens come before the ones.
There are other comparable incongruences between written and spoken symbol order which don't seem to bother anyone.
For example: in English, we say F sharp and B flat. How would you react if someone suggested that English-speaking people should change their note names to "sharp F" and "flat B", because in staff notation, the accidental comes before the notehead?
