There's a limit, but it is the number of DDnames, which relates to the TIOT size for your system. If it is 32K, 1,600+ shouldn't be a problem for something simple, although there are some limits about the amount of code you have.
ICETOOL does lots of useful stuff, mostly by telling DFSORT to do part of it. A lot of "complicated" things can be done in straight DFSORT. ICETOOL has a number of useful operators to do things which would be obtuse in SORT itself (RESIZE, for instance).
ICETOOL operators can also be combined in one set of control cards, so you can do multiple operations in one step to produce a combined result.
If you wanted to copy 86 files to 86 other files, that could be done in one ICETOOL step. You want to split a single file into 80+, which SORT is going to do for you without needing to wrap ICETOOL around it.
Have a look at the DFSORT Getting Started guide.
