Yep. The output will get fixed too, but that's for a little later...

[sage-devel] Re: [sage-cloud] Install SciLab components & create/enable %julia for worksheets?
Hi,
I fixed the scilab problem. Restart your Sage Worksheet Server
(lower left in project settings) to see the fix (and scilab now
working). Note that output in worksheets looks a little funny, due to
control codes.
The scilab problem was a bug in Sage... or rather something in the
command line options to scilab changed as scilab evolved, and Sage
didn't keep up.
I posted something to the Sage trac about this:
http://trac.sagemath.org/ticket/17043
I would really appreciate it if somebody could make this into a proper
branch, etc. and make sure it gets into sage. I put the 2-line patch
in the ticket description. Unfortunately, these days that's
a ton of extra work beyond just posting what needs to be changed, and
I would rather spend time working on SMC itself.
Similar remarks apply about
http://trac.sagemath.org/ticket/17044
which fixes (changing just a few characters) a longstanding
permissions issue that broke many pexpect interfaces for a system-wide
install, and in particular broke the scilab interface.
