Sorry for the delay.

Make that
  scilex_LDADD = routines/libscilab.la

and make sure that it gets built before the program.  If
routines/libscilab.la is built from the same Makefile.am, that should
happen automatically, given that you do _not_ have set
scilex_DEPENDENCIES.  (If you have, you have to add the library in there
manually.)

If the library is built from a different Makefile.am, make sure to have
the proper build order so that it is built before the toplevel; see
  info Automake Subdirectories

The space in `routines/libscilab.la '
                                   ^

looks fishy to me.  Is that a cut'n'paste error?

No, you should not use -lscilab.

Maybe if you still can't get things going, post an URL where we can see
the files, or a small example package that exposes the problem.

I'm sorry, I don't understand this question.  Maybe reading
  info Automake 'Program and Library Variables'

helps?
