without testing it looks like that should throw an error in Scheme when
you try to set! the variable Transpose::Interval to the expression
following, which is
( "c d" 2 Transpose::Interval (_ "-->> Transpose to -->") )
That expression can't evaluate to anything because the first thing in
this list, the string "c d", is not a procedure - a list is evaluated
by executing the first element with the following elements as
It looks like you would mean to write
(set! Transpose::Interval "c d")
where the first element set! is a procedure that sets the second
element (a variable) to the value of the third element (a string).

Not sure, but it looks like it. Try evaluating
(d-InfoDialog (format #f "~s" Transpose::Interval))
in the Scheme window to find out...
But I don't think changing that value will help - what you need to do
is create an example of this staff and then clone the staff
directive(**) as a button to be clicked to apply that transposition to
the current staff. Then you can copy(*) the Scheme script that this
button executes and use it in your script to set the transposition of
the current staff.
(*) right click the button and choose Get Script into Scheme Window
(**) you will find the staff directives under the staff properties
editor - click on the staff number right at the start of the staff.
