my guess is that the change in wording was probably in response to growing anti-affirmative action sentiment. i remember reading in the LA Times recently that many universities criticized for having minority-specific scholarships, etc have opted to revise their policies.
not that i'm a huge champion of affirmative action, but i would think that private universities like stanford or pepperdine have the right to support under-represented minorities with such programs and scholarships

From the LA Times, January 22, 2004:
"Last month, two activist groups lodged complaints about the scholarship ? the Richard Eamer Scholars Program ? with the U.S. Department of Education's Office for Civil Rights. The groups ? including a Sacramento-based organization founded by University of California Regent Ward Connerly ? have formally targeted a half dozen schools around the country, and sent warning letters to as many as 100 institutions.
In California, two other schools ? the California Institute of Technology and Stanford ? have received letters. Each, in turn, modified their practices in a recruiting or fellowship program. But Pepperdine, which received a warning letter but refused to change the Eamer scholarship, was the only California school to draw a formal complaint. "
