That should work fine.  What sort of error are you getting?

/some/path/to/our/target/prog should be in sudoers, with
exactly that path of course.

A note with "$@"  -- most shells have what I would call a bug
in that if there are no args supplied, "$@" evaluates to "".
Whereas you really want nothing at all.  Sudo might object
to getting an arg, even if it's empty.

Try using ${1:+"$@"} instead.  It means:
if $1 is defined (i.e. there are any args at all)
use "$@", i.e. all the args properly quoted.

if $1 is NOT defined, (i.e. no args are given)
then use nothing at all.
