Actually Aaron Hosford just recommended 
 1 / (1 + | a - b | )
Which I like much better. 
Thanks Aaron.

Thanks to all respondents. 
In the end I found a classic numeric similarity metric:    1 - | a - b |
It's not ideal since numeric scores can dominate other attribute scores.Ergo, I 
have to devise a good weighting scheme.
Nothing's perfect I suppose.
Cheers,
