it does.. but only in that it was derived fro ma game that used hexmaps and had a big mismatch of unit scale vs map scale. if you go read the Miniatures rules rulebook for regular BT (you can down load it) you've basically got the core of the AS terrain rules.
personally, i'm ignoring the mapscale issue, and making terrain that visually matches the figures.. AS doesn't have a 'scale' specifically anyway.. they go out of their way to avoid saying how far each inch is supposed to represent, or how long each turn represents in seconds, etc. partly because it really confuses things in that its using Battleforce type rules (where each turn represents half a minute, and each hex represented almost a full mapsheet) with regular battletech movement and ranges. if they got into issues of scale, they'd have ot explain why the mechs are only moving 1/3th the distance they ought to be given the damage and such is based on battleforce 30 second periods.. :)
it's better to treat it akin to warhammer or other games that were originally 3D to start.. scale is "matches the figures" and distances and time are left vague/abstracted for ease of play. things like 1" = 1 level then just becomes record keeping, not scale. O0
