I bet that i is integer here.  Look:

hzoli% select i in aaa bbb ccc
do echo $i
done
1) aaa  2) bbb  3) ccc  
?# 1
aaa
1) aaa  2) bbb  3) ccc  
?# 

hzoli% integer i              
hzoli% select i in aaa bbb ccc
do echo $i
done
1) aaa  2) bbb  3) ccc  
?# 1
0
1) aaa  2) bbb  3) ccc  
?# 

Ksh behaves exactly the same way.  This is not a bug.  Add unset i before
select and it'll work.  Note that i becomes integer if it is initialised
first in an arithmetic expression, like let i=0 or $((i=0)).
