Um...you have done absolutely nothing to make "the practice" seem more acceptable. You have done a great job in making yourself out to be a giant, stubborn douchbag who thinks one test score makes him worthy of getting a job. I really think you are severely underestimating the negative impact this will have on people viewing your application. I for one would immediately dislike you as an applicant if I saw your lsat score. You'd have to have something pretty spectacular to overcome that much of a negative reaction (and let's face it - if you had something spectacular, you wouldn't be putting your lsat score on your resume anyway).
You LSAT says pretty much nothing about you other than your ability to take a standardized test. As a lawyer, I couldn't care ANY less about that particular skill. I care about how you did in undergrad, about how you did in law school, and about your activities, work experience and life experience. So even if you don't immediately turn someone off by the LSAT score, you still seem to be showing poor judgment. Every single word on your resume should be geared toward showing an employer that you'd be valuable to them. Anything that doesn't do so needs to go. You're wasting the employer's time with anything that doesn't achieve that, and that's the last thing you want to do when that decision-maker is sifting through a huge stack of resumes.
