In this paper we examine certain recent generalizations of the topological property "X is perfect," i.e., closed subsets of X are Gδ-sets, to determine which are equivalent to being perfect in the category of generalized ordered spaces. We use these results to give necessary and sufficient conditions for X* and L(X), the two most common linearly ordered extensions of the generalized ordered space A, to be perfect.
