And for that very purpose "Plot on Sorted Lines" filter was recently added to CVS. It sorts the points so that the numbering of vertices is monotonously increasing. For the multiblock-case, you'll have to do a couple of operations: Merge Blocks -> Extract Surface -> Plot on Sorted Lines which will merge the multiblock into a single dataset and then sort and plot them.
