First of all -the Mechaber says to give to a Shul is more important than Tzedaka and giving money to a child to learn Torah or to a sick poor person is even more important.
I don’t understand how you counter the point that support for Torah comes before poor people with the fact that giving to a shul takes precedence over giving to poor people.
As to which takes precedence, adult Torah scholars or children’s Torah, it’s a machlokes, and it depends on multiple factors. See this article, footnote 6, for some sources.
Please inform if you know of anyone who argues on the general precedence of Torah support over most other forms of tzeddakah (more authoritative than some comment, probably taken out of context, from Rabbi Krohn).
