I can't reproduce (Debian 7 Jessie, GNU Octave 3.7.7+)
x = logspace(0,2,100);
y = 0.1*x.^3;
loglog(x,y)
grid on
set(gca,"xminorgrid","on")
print -dsvg "test.svg"

Saves an SVG with all grids on it. I daresay that you problem is due
to the library used to generate SVG, in case fltk it seems to be
gpl2ps and I do not know what gnuplot is using (my case).
