"4750
"

When taken in a list context, backticks return one line per list item. 
Thus you may be able to take merely the first list position to get what 
you want:

  # Only want the first line of output returned.
  my $mode = ( `svn propget file:mode "$filename"` )[0];

I'm not sure why chomp isn't working.

I hope this helps.
