This is really what your bug report is about, I think. :)

There are several ways, all of them slightly awkward:

1. Redefine the articulation and add a tweak:

staccato =
#(let ((stacc (make-articulation "staccato")))
   (set! (ly:music-property stacc 'tweaks)
         (acons 'toward-stem-shift 1
          (ly:music-property stacc 'tweaks)))
   stacc)

This isn't much use for any script which has a shortcut though.

2. Shadow the default alist entry in default-script-alist:

\layout {
  \context {
    \Score
    scriptDefinitions =
    #(cons
      `("tenuto"
        . ((script-stencil . (feta . ("tenuto" . "tenuto")))
           (quantize-position . #t)
           (avoid-slur . inside)
           (padding . 0.20)
           (side-relative-direction . ,DOWN)
           (toward-stem-shift . 1)))
      default-script-alist)
  }
}

Really we should have some kind of infrastructure for easily tweaking
individual Scripts (a music function would probably do it, in a
similar way to the second method above), though there's an interesting
alternative suggested in script-engraver.cc whereby each script type
would generate an equivalent grob which inherits defaults from Script
but is called Script*Name* (e.g, ScriptStaccato or ScriptPrall).  This
would allow you to override properties for a specific type easily
(and, as it says in the engraver, save a bit of memory too).

OK, will do.  I assume your edition of Wozzeck is from UE (just
checking so I know what to mention in the docstring)?
