The Lua operator .. is string concatenation, so you can do:
"foo" .. "bar"
to get:
"foobar"

Something like:
-- called when "greaterthan" message is received at first inlet
-- atoms is a table of the atoms in the message following the selector
function M:in_1_greaterthan(atoms)
local name = atoms[1] -- could be: "score"
local value = atoms[2] -- could be: 3
if name ~= nil and value ~= nil then -- could check types too..
-- do your stuff here
end
end
If you have a range of possible selectors, and don't want to have to
write a method for all of them, you can use:
function M:in_1(selector, atoms) ... end
Then selector will be "greaterthan" (or whatever) and atoms will be as
above.
More specific methods are called before less specific methods, read
pd.lua to see how that works (it's in the dispatcher function(s)).
Hope this helps,
Claude
