This is definitely a bug, which could be fixed.  In the meantime, as a workround 
you might just do

"<p>Let  $a < b$.</p>"

since that will look better anyways.

I can't tell if I'm seeing the same problem or not, so I have a new ticket which might be related: #4316.

When testing the problem in #4316:

%html 
some math: $x<y$.

I get the message

NameError: global name 'cgi' is not defined

More importantly, when testing the problem reported here, I don't see a change in behavior: after editing the worksheet and typing

<p> Let <i>a&lt;b</i>.</p>

in between cells and saving, it looks fine, but when I click "Edit" again, the < has turned into <, and it is printed wrong.

Mike's patch above breaks %html mode since it assumes you literally want "<" every time you write it. That means you can't type <b>hello</b>. I like it better the other way (before), that demanded that you type < instead of <.

This is somewhat of a moot point now that TinyMCE is in.
