Does your termcap entry for xterm contain Co#256? That's how screen
detects if your terminal supports 256 colors. Maybe adding

    termcapinfo xterm Co#256

does the trick for you. (Of course you might need AB/AF as well).
Note also that the xterm termcap entries that ship with the xterm
program contain:

# These aliases are for compatibility with the terminfo; termcap cannot provide
# the extra features, but termcap applications still want the names.
x1|xterm-16color|xterm alias:tc=xterm-xfree86:
x2|xterm-88color|xterm alias:tc=xterm-256color:
x3|xterm-256color|xterm alias:tc=xterm-xfree86:
xn|xterm-nrc|xterm alias:tc=xterm:
xr|xterm-rep|xterm alias:tc=xterm:
xx|xterm-xmc|xterm alias:sg#1:tc=xterm:

In other words, they don't support the color codes. But maybe your
termcap contains different entries.
