Ah, yes, I did miss that.  Compensating for that, the typical 
commercial flight altitudes see temps ranging from about -30C down to 
what looks to be about -57C.

Cold enough that nylon ties in unheated areas will be experiencing 
chill levels often dangerously close to their brittle point.

If they were behind the panel, that would still be in the portion where 
the temp is not -30C to -60C (otherwise you'd be rather chilly and 
uncomfortable yourself).  So still plenty of safety margin left before 
brittleness would become a factor there.
