strange behaviour of ListPlot with PlotStyle options in Mathematica 9

Hi there,

In Mathematica 8.0.4 both commands below show a graph in red color.

ListPlot[RandomReal[10, 20], Joined->True, PlotStyle->{{Red},{Green},{Blue}}]

ListPlot[{RandomReal[10, 20]}, Joined->True, PlotStyle->{{Red},{Green},{Blue}}]

However, in Mathematica 9.0, the first command line shows a blue graph and the second one a red graph.

I used to have my customized PlotStyle options as a list of attibutes, but when I have just one set of points to graph, Mathematica 9 picks up only the last  attribute of the list instead of the first one (as I think it should be).

It seems that something changed with the new version of Mathematica about how the Plot options are read.
