The simple explanation is that the fontSize property is handled by the
Font_size_engraver, which by default lives in the Staff context. Since
the PianoStaff instrument names are typeset at the PianoStaff level, it
means that the value of fontSize isn't used, then.
One solution is to add the engraver also at the PianoStaff level:
\layout{
\context{
\PianoStaff
\consists "Font_size_engraver"
}
}
As far as I can see, this does not influence how the fontSize property
is handled at the Staff level, so there should be no negative side-effects.
An alternative, is to explicitly set the font size for the instrument names:
\new PianoStaff \with { \override InstrumentName #'font-size =
#(magnification->font-size 2/3) ... }

Hello,
while working with lilypond I discovered that changes of the font size
are
treated differently between Staff and PianoStaff.
Consider the following snippet:
\version "2.13.4"
stuff = \relative c {
c4 d e f
g a b c
}
\score {
<<
\new Staff = "Staff" \with { \override StaffSymbol #'staff-space =
#2/3
fontSize = #(magnification->font-size
2/3)
instrumentName = #"Staff" }
{ \clef "treble" \stuff }
\new PianoStaff = "PianoStaff" \with { \override StaffSymbol
#'staff-space = #2/3
fontSize =
#(magnification->font-size 2/3)
instrumentName =
#"PianoStaff" }
<<
\new Voice = "RH" { \clef "treble" \stuff }
\new Voice = "LH" { \clef "bass" \stuff }
>>
>>
}
The "Staff" is scaled properly, whereas "PianoStaff" is not. I didn't
find anything in the bug tracker,
but this seemed to be not the desired behavior.
