At first I thought that it is a pure latex problem which should
better go at comp.text.tex or the lualatex mailing list. But it
could be that there is (context) font code or luatex problem.

With ConTeXt  ver: 2011.06.13 23:08 MKIV  fmt: 2011.6.15  (from the
minimals) the following fails:

\starttext

\font\test=file:fxlr.otf
\test abc \letterspacefont\lspfont=\font 500 \lspfont blub

%breaks: letterspaced font is not small small caps:
\font\test=file:fxlr.otf:mode=node;+smcp
\test abc \letterspacefont\lspfont=\font 500 \lspfont blub

%letterspacefont works:
\font\test=file:fxlr.otf:mode=base;+smcp
\test abc \letterspacefont\lspfont=\font 500 \lspfont blub

\stoptext

(fxlr.otf are the linux libertine O fonts as you get them in the
libertine package on CTAN. But probably the problem can be tested
with every font where small caps are implemented with +smcp).
