The StringResourceModel uses MessageFormat patterns, so you could try
using a ChoiceFormat-based pattern. Try this out in a main method
somewhere to get an idea of what happens:
final String pattern = "{0,choice,0#none|1#one|2#couple|2<many}";
System.out.println(MessageFormat.format(pattern, 0));
System.out.println(MessageFormat.format(pattern, 1));
System.out.println(MessageFormat.format(pattern, 2));
System.out.println(MessageFormat.format(pattern, 100));
