Speculation: Or it doesn't. Maybe it submits the rebuilds in dependency
order but it does the builds against vanilla koji repository. And that's
all only to prevent from continuing in rebuilding reverse dependecies if
a package has failed.

I worry the Koschei is just a packager-space tool without any
koji-releng-priviledges for creating tags. I heard using offical koji
instance is one of the design decisions.

Maybe perl-Fedora-Rebuild could satisfy your desire. It can do dependency
ordered bootstrap in mock or in koji. (Bootstrap means you define
a pattern for a dependency symbols of interest, e.g. /perl\([^)]*\)/,
and then the build order is computed on this constrained set of
dependecies starting from empty set---thus the bootstrap.)
