I cannot test since lilypond is not working properly on my computer,
but I get the proper numbers.

Here's an excerpt from the log file (I changed lilypond to echo):

systems         : begin file test1 at line 2
<test1-lilypond-1.tmp>
system(echo test1-lilypond-1.tmp)...executed.

system(epstopdf test1-lilypond-1.eps)...executed.

 (C:\Programi\MikTeX\tex\context\base\pdfr-ec.tex)
figures         : figure test1-lilypond-1 can not be found
color           : mpcmyk color space is supported
color           : mpspot color space is supported
color           : system rgb is local activated
<test1-lilypond-2.tmp>
system(echo test1-lilypond-2.tmp)...executed.

system(epstopdf test1-lilypond-2.eps)...executed.
