The -scene setting does not seem to effect the fx: 't' variable.
Remember 't' is the 'index' and as such started at '0'.

One way of finding out what the value of the fx expression is to use

   convert rose: \( +clone \) \( -clone 0--1 \) \
           -scene 100 -set label '%[fx:t]' -format %l info:
   0
   1
   2
   3

Note that the number of images variable 'n' does not work at this time.
At least not outside the full "-fx" operator.
