Since people were asking for a less US-centric political test I tried to find one. The one at The Political Compass
seems to fit the bill pretty well. The results aren't a simple single number, instead they're plotted on an x/y graph.
Economic issues are the X axis liberal being the negative, conservative being positive.
Social issues are the Y axis, again, liberal being negative, conservative positive.
My score was Economic: -7.75 Social -6.82
