     Here's one way:

z = boxplot(mydata$score,outline=FALSE,ylim=range(mydata$score))
text(1,z$out,SubNo[which(score == z$out)])

You can avoid the explicit setting of ylim (although I would
normally prefer setting it) and use instead:

 z <- boxplot(mydata$score, outpch="")
 text(1, z$out, SubNo[which(score == z$out)])

But note that this only works for a single outlier.
Assuming that your use of SubNo is merely to identify
the score maximum, you might as well use

 with(mydata, boxplot(score, outpch = as.character(which.max(score))))

How can I get the outlier in this boxplot of "Score" to be represented by
the corresponding value in "SubNo"?

score=c(6,6,7,14,5,7,6,8)
SubNo=1:8
mydata=data.frame(SubNo, score)
boxplot(mydata$score)


Thanks!
Kevin
