?mtext shows you that  "adj" really only uses one number, i.e., in your
case 0.5 = the default ...
		       [one could argue it should give a warning in your case..]

I don't see any problem;
here is some illuminating code :

  eval(ex <- quote(par(oma=c(3,3,.2,.2))))
  plot(1); mtext(deparse(ex))
  box("inner", lty="dashed", col = "light blue")
  for(a in seq(-.1,1.1,by=.1)) {
      mtext(expression(sigma),1,        outer=TRUE, adj= a)
      mtext(format(a),        1,line=1, outer=TRUE, adj= a)
