They're not going to hold when you screw them back either, so the 
best thing to do -- and I have done it on several jobs much younger 
than that -- is to cut away and insert new blocks of wood (beech over 
here).  You can also get a set of replacement action supports from 
Steinway, but it's just as much work, if not more.  Once these screws 
have been over-turned, there is no other serious remedy.
