The -regex option with a find that supports it is BRE regex, which means that the curly braces will need to be escaped with a backslash otherwise it means a literal brace..
There was a closing brace too many in my example (one escaped, one unescaped). Corrected it in my post..
But that will match any occurrence of 1 or more numbers before the dot. To only match 1-3 numbers there needs to be another "anchor" before the numbers:
Try:
to specify that the number is preceded with a dash, or
to specify that the number is preceded by a character other than a number..

regex.h(3HEAD) Headers regex.h(3HEAD)NAME
regex.h, regex - regular expression matching types
SYNOPSIS
#include <regex.h>
DESCRIPTION
The <regex.h> header defines the structures and symbolic constants used by the regcomp(), regexec(), regerror(), and regfree() functions.
See regcomp(3C).
The structure type regex_t contains the following member:
size_t re_nsub number of parenthesized subexpressions
The type size_t is defined as described in <sys/types.h>. See types.h(3HEAD).
The type regoff_t is defined as a signed integer type that can hold the largest value that can be stored in either a type off_t or type
ssize_t. The structure type regmatch_t contains the following members:
regoff_t rm_so byte offset from start of string to start
of substring
regoff_t rm_eo byte offset from start of string of the
first character after the end of substring
Values for the cflags parameter to the regcomp function are as follows:
REG_EXTENDED use extended regular expressions
REG_ICASE ignore case in match
REG_NOSUB report only success or fail in regexec()
REG_NEWLINE change the handling of NEWLINE character
Values for the eflags parameter to the regexec() function are as follows:
REG_NOTBOL The circumflex character (^), when taken as a special character, does not match the beginning of string.
REG_NOTEOL The dollar sign ($), when taken as a special character, does not match the end of string.
The following constants are defined as error return values:
REG_NOMATCH regexec() failed to match.
REG_BADPAT Invalid regular expression.
REG_ECOLLATE Invalid collating element referenced.
REG_ECTYPE Invalid character class type referenced.
REG_EESCAPE Trailing '' in pattern.
REG_ESUBREG Number in fIdigit invalid or in error.
REG_EBRACK "[]" imbalance.
REG_EPAREN "()" or "()" imbalance.
REG_EBRACE "" imbalance.
REG_BADBR Content of "" invalid: not a number, number too large, more than two numbers, first larger than second.
REG_ERANGE Invalid endpoint in range expression.
REG_ESPACE Out of memory.
REG_BADRPT '?', '*', or '+' not preceded by valid regular expression.
REG_ENOSYS Reserved.
