GRE score consideration for PhD and MA programs in philosophy has been shown to do more harm than the amount of helpful information it provides about applicants to admissions committee.  Michael Weisberg to my knowledge has put the problem best:

"The GRE can be financially burdensome for low-income applicants ($205 for the general test in the USA, only 50% of which is waivable by the ETS, plus the non-waivable $27 per school to send your scores to after 4 schools) and offer unfair advantages to wealthy applicants (e.g. ETS offers a score review service for an extra fee and Kaplan offers test prep services for a fee that isn't entirely waivable). Second, GRE scores do not, in general, accurately predict academic performance in graduate school (e.g. Q,V, & AGRE scores explain only 4.4-7.8% of graduate GPA variance according to replicated studies). Third, significant gaps in GRE performances by women and underrepresented racial and ethnic minorities made it especially difficult for them to be accepted, even though their scores sometimes dramatically underpredicted their academic performances in our program. Fourth, in our judgment, nothing of significant epistemic value was gained by our use of the GRE that we couldn't figure out from looking at transcripts, writing samples, etc." 

The only way to solve these problems, short of writing a better, more accurate test, is to cease consideration of GRE scores for philosophy PhD and MA programs.
