If there is not much data to be recorded I have used the document metadata to store the information required for the run twice types of scripts. I use in actions.

// This script is designed to be used by a Photoshop Action twice
// A good pratice to use when creating an actions that use this scipt is for the action
// not to do a save or play some other action between its two useages of this Script.
//
// This script will look at the document orientation (portrait vs landscape)
// On the first execution, if the document is a portrait, it will be rotated
// to a horizontal.
// On the second execution, a rotated document will be
// restored to a vertical. This effectively toggles the orientation ONLY if
// the original document started out as a portrait.
//
// NOTE: Meta-data Info Instructions field is modified to hold an interim state.
//
// Bug Fixes by JJMack, 2008, with the original code Square images were always
// rotated -90 and marked "rotate back" with two executions you wound up with
// an upside down image... The original code would also fail to rotate an image
// back if the action added canvas and change the rotated images aspect ratio
// to other then landscape. Again you wind up with a marked upside down image.
// In addition units the compare could fail because the script did not set the
// units to use for rulers.
//
// Updated in 2009 JJMack to remove some restrictions try make it near bullet proof
// presserve any data that might have been in Files metada Info Instructions field
// this also allows more one run twice scripts to be used on a document.
