You may need to provide further clarification, as the most common
reference to a score test in LR seems to be for testing the proportional
odds assumptions behind that particular approach.

If this is correct, there is a worked example in V&R's MASS 4 (the book)
on page 204 with respect to the use of the polr() function in MASS (the
package.)

An alternative is in Frank's Design package, where using ?residuals.lrm
will provide some examples, including diagnostic plots.

HTH,
