As a first step toward circumventing the difficulty to obtain an attractiveisospin-independent NN spin-orbit force from Skyrme-type models involving onlypions, we investigate an improved Skyrme Lagrangian that incorporates thescalar-isoscalar meson \epsilon which can be viewed as the cause behind theenhancement of the $\pi \pi S$-wave. We find that at large distances, the maincontribution to the spin-orbit potential comes from the scalar Lagrangian andit is found to be attractive. We briefly discuss how to pursue this work tofinally obtain a medium-range attractive interaction.Comment: 10 pages (revtex) + 2 figures; use \psfig command. Minor changes in  the text and some discussion added in the last section. To be published in Z.  Phys.
