I'm not sure what sort of versioned dependency you're referring to, but
config scripts can only use binaries from essential packages or debconf
itself.  See debconf-devel:

       Note that the config script is run before the package is unpacked.
       It should only use commands that are in essential packages.  The
       only dependency of your package that is guaranteed to be met when
       its config script is run is a dependency (possibly versioned) on
       debconf itself.
