Being very simple minded, I would have run something like:
l2 <- lmer(score ~ sex * condition + (1 + condition | subject), data=d)
l1 <- lmer(score ~ sex + condition + (1 + condition | subject), data=d)
l0 <- lmer(score ~ condition + (1 + condition | subject), data=d,
            subset=complete.cases(sex))
anova(l2, l1, l0)
