The problem is that
zoom_sensitivity_ratio is a client cvar. It cannot be retrieved with
get_user_info. By
get_user_info, you can retrieve any information from
setinfo structure (which can be viewed by using setinfo command).
Field
rate is a part of setinfo structure - that's why it's possible to get it.
This issue is very simmilar to the one with
fps_max cvar. Many think that it's possible to get this value with this function (as it's written in example in funcwiki) - but it's meretricious disinformation.
I suggest using
THIS function instead. I have no experience with it.
Edit: And as I read previous posts, it was suggested already. You should read carefully what they advice you. The way you're doing it won't work.
