Hi Linan, http://docs.neo4j.org/chunked/snapshot/tutorials-java-embedded-traversal.html#_new_traversal_framework has an example of an ordered path, does that help? The code for it is at https://github.com/neo4j/community/blob/master/embedded-examples/src/test/java/org/neo4j/examples/orderedpath/OrderedPathTest.java
Also, Gremlin, as Marko states, is applicable here.
