Definition of range3 is incorrect in SMath. The correct definition should read range 3 returns a vector that starts at number 1 and ends at number 3 with an increment of number 2 minus number 1.
Number 2 and 3 have been interchanged.

There's no error. The argument enumeration for any function in SMath Studio is given in the input order (the one you can see even by pasting the math as plain text); accidentally in range(3) the glyph has the three arguments in a row with the 3rd one in the middle, hence probably the confusion

range(1,2,3) ->

Thanks Davide - I get it now
