The problem is you are using text relational operators ('>=') to compare numeric values. With a text compare, 100 is less than 4 because it does a lexical comparison. You must use numeric relationals, as in '>=#'. See "Relational operators" section in The calibre template language.

Here is your template, corrected.

count = raw_field('#chapters');

chapters_count = switch_if(
    count >=# 100, 100, count >=# 95, 95, count >=# 90, 90, 
    count >=# 85, 85, count >=# 80, 80, count >=# 75, 75, 
    count >=# 70, 70, count >=# 65, 65, count >=# 60, 60, 
    count >=# 55, 55, count >=# 50, 50, count >=# 45, 45, 
    count >=# 40, 40, count >=# 35, 35, count >=# 30, 30, 
    count >=# 25, 25, count >=# 20, 20, count >=# 15, 15, 
    count >=# 10, 10, count >=# 5, 5, count >=# 1, 1, 0);
