Is there a way to easily specify a line color from the (relatively) new default line color ordering? What I'd like is to be able to replace the command
>> plot(x,y,'b-o')
with something that gives the new default blue that's different from 'b'.
If not, and I assume not, then let me make this a feature request. Can you make the command
>> plot(x,y,'1-o')
plot a line with the first color in the default ordering, etc?
This would be useful if I plot a line using 'plot(x,y)' and somewhere down the line want to add another line to the plot that is the same color.

You can specify the color of a line not only via a LineSpec but also via specifying the line's 'Color' property in the plot call.
ax = axes;
hold on
for k = 1:20
h = plot(1:10, 1:10, '-o', ...
'Color', ax.ColorOrder(ax.ColorOrderIndex, :));
pause(0.5)
end
This will plot a new line 20 times with half a second pause between each plot, each time using the next color in the ColorOrder property of the axes.

You can define any colors col and do
col = jet(5);
set(gca,'colororder',col)

Oh, I see what you mean. I realize this is not the solution you're seeking, but I think I'd write a new function called myplot that would parse the inputs and then call plot.
