how to control the node numbering?

a set of 100nodes (all connected as a straight line) was define from a large node sizes (lets say is 1000), i want to renumber the set follow a sequence (lets say from left to right, 1 to 100) ...but after i renumbering them, the set doesn't follow the desired sequence...so how to solve it...any expert..?

although this could be manually done by clicking one by one until hundread...but problem came when the node set is too large (click until your mouse spoiled...haha)
