There are termcap entries in Darwin, referring to terminals called "Apple_Terminal", "Apple_Terminal+acs", "Apple_Terminal+mac", etc.

Here's what I have in my .zshrc so I can get Terminal to be properly recognized elsewhere (I haven't copied the termcap entries everywhere):

case $TERM_PROGRAM in
  Apple_Terminal)
    if [[ $TERM == "screen" ]] {
      unset TERM_PROGRAM; export TERM_PROGRAM
    } else {
      if [[ -z $DISPLAY ]] {
          export TERM=vt100
      }
    }
    ;; 
  GLterm)
    if [[ $TERM == "screen" ]] {
      unset TERM_PROGRAM; export TERM_PROGRAM
    } else {
      if [[ -z $DISPLAY ]] {
          export TERM=xterm-color
      }
    }
  esac

if [[ $TERM == "xterm-color" || $TERM_PROGRAM = "Apple_Terminal" ]] {
    xterm_prompt=1
    prompt="[%U%l:%h%u] %~%#"
}

chpwd() {
  [[ -t 1 ]] || return
  if [[ -n $xterm_prompt ]] {
      print -Pn "e]2;${USER}@${HOST}:%~a"
  }
}

etc.

Here is how I've expressed it in CSH:

if ( $TERM_PROGRAM == Apple_Terminal) then
        setenv TERM vt100-color
endif
