Have you tried?
If it is a grob property...

Check out the following example where I just add a few lines in front of
what you wrote:
#(define (define-grob-property symbol type? description)
(if (not (equal? (object-property symbol 'backend-doc) #f))
(ly:error (G_ "symbol ~S redefined") symbol))
(set-object-property! symbol 'backend-type? type?)
(set-object-property! symbol 'backend-doc description)
symbol)
#(define-grob-property 'bar number? "Werner's specialty")
#(define-markup-command (foo-markup layout props) ()
#:properties ((bar 10))
(interpret-markup
layout props
#{
\markup \fontsize #bar \natural
#}))
foo =
#(define-music-function () ()
#{
\tweak parent-alignment-X #CENTER
\tweak self-alignment-X #CENTER
-\markup \foo-markup
#})
{
f'2-\foo
f'2-\tweak bar #5 \foo % This tweak (expectedly) fails.
}
